HEAT SINKS for MULTI-MODE TRANSMITTERS
Quasonix offers a number of heat sinks for use with TIMTER™ transmitters and nanoTX™ transmitters.
The heat sink required for a particular transmitter depends heavily on the installation. Factors such as
altitude, air temperature, air flow, and mass of the mounting surface all have a substantial impact on the
flow of heat away from the transmitter.
It is important that the bottom surface (the face opposite the product label) be securely attached to a
baseplate capable of dissipating the power produced by the transmitter model in use. This mounting
baseplate must be flat, smooth, and clean.
Quasonix offers different types of integrated and add-on heat sinks, as described in this datasheet. Please
contact Quasonix for heat sink recommendations for your particular TIMTER™ transmitter.
Regardless of the heat sink, Quasonix strongly suggests using a thermal pad, such as Tpcm™ 583 from
Laird Technologies.
 Fan-cooled Heat Sink
(P/N QSX-AC-32-HS-12V)
The copper heat sink with fan is compatible with most
TIMTER™ and nanoTX™ models. It includes a power
supply for North American operation.
ISO 9001:2015 Certified
 Transmitter-powered Heat Sink
(P/N QSX-AC-32-HS-28V-SP)

This heat sink has an integral fan, power supply, and
temperature-controlled power on at +37°C. Two MDM15 connectors and a provided pigtail cable allow the
heat sink to draw power directly from a TIMTER™
transmitter, eliminating the need for a separate
external power supply.
By regulating fan speed to compensate for changes in
air pressure/density under high altitude conditions,
Quasonix' transmitter-powered heat sink provides
thermal protection for a variety of applications.
The male and female heat sink connectors, along with
the dual-gender cable, enable connection to any
TIMTER™ transmitter. An SMA extender is included to
ensure convenient RF connector access.

ATTENTION: Do not operate the transmitter without a proper heat sink. Failure to
do so may lead to permanent damage to the unit and will void the warranty.
Overheating can occur in a matter of seconds when a transmitter is not properly heatsinked. In absolutely no case should any type of stickers or labels be applied to the
bottom surface of the transmitter.
