Soldering
1.1
SMD NTC thermistors
SMD NTC thermistors can be provided with a nickel barrier termination or on special request with
silver-palladium termination. The usage of mild, non-activated fluxes for soldering is recommended as well as a proper cleaning of the PCB.
Nickel barrier termination
The nickel barrier layer of the silver/nickel/tin termination (see figure 1) prevents leaching of the
silver base metalization layer. This allows great flexibility in the selection of soldering parameters.
The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The
nickel barrier termination is suitable for all commonly-used soldering methods.

Conductive adhesion
An alternative to soldering is the gluing of thermistors with conductive adhesives. The benefit of
this method is that it involves no thermal stress. The adhesives used must be chemically inert.
3
Sealing and potting
When thermistors are sealed, potted or overmolded, there must be no mechanical stress caused
by thermal expansion during the production process (curing / overmolding process) and during
later operation. The upper category temperature of the thermistor must not be exceeded. Ensure
that the materials used (sealing / potting compound and plastic material) are chemically neutral.
4
Cleaning
If cleaning is necessary, mild cleaning agents such as ethyl alcohol and cleaning gasoline are
recommended. Cleaning agents based on water are not allowed. Ultrasonic cleaning methods are
permissible.
5
Storage
In order to maintain their solderability, thermistors must be stored in a non-corrosive atmosphere.
Humidity, temperature and container materials are critical factors.
Do not store SMDs where they are exposed to heat or direct sunlight. Otherwise, the packing material may be deformed or SMDs may stick together, causing problems during mounting. After
opening the factory seals, such as polyvinyl-sealed packages, use the SMDs as soon as possible.
The components should be left in the original packing. Touching the metallization of unsoldered
thermistors may change their soldering properties.
Storage temperature:
25 °C up to 45 °C
Relative humidity (without condensation):
≤75% annual mean
<95%, maximum 30 days per annum
Solder the thermistors listed in this data book after shipment from EPCOS within the time specified:
SMDs:
12 months
Leaded components:
24 months

Placement and orientation of SMD NTC thermistors on PCB
a) Component placement
It is recommended that the PC board
should be held by means of some
adequate supporting pins such as
shown left to prevent the SMDs from
being damaged or cracked.
b) Cracks
When placing a component near an
area which is apt to bend or a grid
groove on the PC board, it is advisable
to have both electrodes subjected to
uniform stress, or to position the
component's electrodes at right angles
to the grid groove or bending line (see
c) Component orientation).
c) Component orientation
Choose a mounting position that
minimizes the stress imposed on the
chip during flexing or bending of the
board.

Cautions and warnings General
See "Important notes" at the end of this document.
Storage
Store thermistors only in original packaging. Do not open the package prior to storage.
Storage conditions in original packaging: storage temperature 25 °C ... +45 °C, relative
humidity ≤75% annual mean, <95% maximum 30 days per annum, dew precipitation is
inadmissible.
Do not store thermistors where they are exposed to heat or direct sunlight. Otherwise, the
packing material may be deformed or components may stick together, causing problems during
mounting.
Avoid contamination of thermistor surface during storage, handling and processing.
Avoid storage of thermistors in harmful environments like corrosive gases (SOx, Cl etc).
Use the components as soon as possible after opening the factory seals, i.e. the
polyvinyl-sealed packages.
Solder thermistors within the time specified after shipment from EPCOS.
For leaded components this is 24 months, for SMDs 12 months.
Handling
NTC thermistors must not be dropped. Chip-offs or any other damage must not be caused
during handling of NTCs.
Do not touch components with bare hands. Gloves are recommended.
Avoid contamination of thermistor surface during handling.
Bending / twisting leads
A lead (wire) may be bent at a minimum distance of twice the wire’s diameter plus 4 mm from
the component head or housing. When bending ensure the wire is mechanically relieved at the
component head or housing. The bending radius should be at least 0.75 mm.
Twisting (torsion) by 180° of a lead bent by 90° is permissible at 6 mm from the bottom of the
thermistor body.
Soldering
Use resin-type flux or non-activated flux.
Insufficient preheating may cause ceramic cracks.
Rapid cooling by dipping in solvent is not recommended.
Complete removal of flux is recommended.

B572**V5
Automotive
Mounting
Ensure that no thermo-mechanical stress occurs due to production processes (curing or
overmolding processes) when thermistors are sealed, potted or overmolded or during their
subsequent operation. The maximum temperature of the thermistor must not be exceeded.
Ensure that the materials used (sealing/potting compound and plastic material) are chemically
neutral.
Electrodes/contacts must not be scratched or damaged before/during/after the mounting
process.
Contacts and housing used for assembly with the thermistor must be clean before mounting.
Ensure that adjacent materials are designed for operation at temperatures comparable to the
surface temperature of the thermistor. Be sure that surrounding parts and materials can
withstand the temperature.
Avoid contamination of the thermistor surface during processing.
The connections of sensors (e.g. cable end, wire end, plug terminal) may only be exposed to
an environment with normal atmospheric conditions.
Tensile forces on cables or leads must be avoided during mounting and operation.
Bending or twisting of cables or leads directly on the thermistor body is not permissible.
Avoid using chemical substances as mounting aids. It must be ensured that no water or other
liquids enter the NTC thermistors (e.g. through plug terminals). In particular, water based
substances (e.g. soap suds) must not be used as mounting aids for sensors.
Operation
Use thermistors only within the specified operating temperature range.
Use thermistors only within the specified power range.
Environmental conditions must not harm the thermistors. Only use the thermistors under
normal atmospheric conditions or within the specified conditions.
Contact of NTC thermistors with any liquids and solvents should be prevented. It must be
ensured that no water enters the NTC thermistors (e.g. through plug terminals). For
measurement purposes (checking the specified resistance vs. temperature), the component
must not be immersed in water but in suitable liquids (e.g. Galden).
Avoid dewing and condensation unless thermistor is specified for these conditions.
Bending or twisting of cables and/or wires is not permissible during operation of the sensor in
the application.
Be sure to provide an appropriate fail-safe function to prevent secondary product damage
caused by malfunction.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or
failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in
which the malfunction or failure of an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by
means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order. We also
reserve the right to discontinue production and delivery of products. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the "General Terms of Delivery for Products and Services in the Electrical Industry" published by the German Electrical and Electronics Industry Association
(ZVEI).
7. The trade names EPCOS, BAOKE, Alu-X, CeraDiode, CSMP, CSSP, CTVS, DSSP,
