Thick Film Chip Resistors / Low Resistance Type
n Recommended Land Pattern
In the case of flow soldering, the land width must be smaller than the Chip Resistor width to control the solder amount
properly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In the case of reflow soldering,
solder amount can be adjusted, therefor the land width should be set to 1.0 to 1.3 times chip resistor width (W).

Cautions for Safety
The following are precautions for individual products. Please also refer to the precautions common to Fixed Resistors
shown on page ER3 of this catalog.
1. Take measures against mechanical stress during and after mounting of Thick Film Chip Resistors (hereafter called the
Resistors) so as not to damage their electrodes and protective coatings.
2. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations
of the Resistors when installed in your products before use.
Never exceed the rated power. Otherwise, the performance and/or reliability of the Resistors may be impaired.
3. Do not use halogen-based or other high-activity flux. Otherwise, the residue may impair the Resistors' performance
and/or reliability.
4. When soldering with a soldering iron, never touch the Resistors' bodies with the tip of the soldering iron. When using a
soldering iron with a high temperature tip, finish the soldering as quickly as possible (within three seconds at 350 ¡C
max.).
5. As the amount of applied solder becomes larger, the mechanical stress applied to the Resistors increases, causing
problems such as cracks and faulty characteristics. Avoid applying an excessive amount of solder.
6. Do not apply a shock to the Resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the Resistors'
protective coatings and bodies may be chipped, affecting their performance.
7. Avoid excessive bend of printed circuit boards in order to protect the Resistors from abnormal stress.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or us
e.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
Caution for Safety
(Common precautions for Fixed Resistors)
¥ When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifications with us in advance. The design and specifications in this catalog are subject
to change without prior notice.
¥ Do not use the products beyond the specifications described in this catalog.
¥ This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products.
¥ Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as damage to
vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
] Systems equipped with a protection circuit and a protection device
] Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault
(1) Precautions for use
¥ These products are designed and manufactured for general purpose and standard use in general electronic
equip ment (e.g. AV equipment, home electric appliances, office equipment, information and communication
equipment)
¥ These products are not intended for use in the following special conditions. Before using the products,
carefully check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent
2. In direct sunlight, outdoors, or in dust
3. In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
4. In an environment where strong static electricity or electromagnetic waves exist
5. In an environment where these products cause dew condensation
6. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials
¥ These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
¥ Carefully position these products so that their temperatures will not exceed the category temperature range due
to the effects of neighboring heat-generating components. Do not mount or place heat-generating components
or inflammables, such as vinyl-coated wires, near these products .
¥ Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the
perfor mance or reliability of the products.
¥ Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance
or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water
residues. Otherwise, the insulation performance may be deteriorated.
(2) Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of arrival
