DESCRIPTION
These directly heated thermistors have a positive
temperature coefficient and are primarily intended for inrush
current generation. They consist of a high grade ceramic
disk with two rugged pattern silver electrodes for contact
pressure mounting. These ceramic pellets can be build into
proprietary motor start devices for compressor, refrigerator
and HVAC OEMs.

MOUNTING
The PTC thermistor pellets are suitable for pressure contact
mounting in application specific housing assemblies.
Examples of such assemblies can be found in the PTC305C
series. Assembly housing must be appropriate for usage up
to 180 °C surface temperature of the PTC pellets.
The pellets are not solderable.

MARKING
The pellets are not marked. Marking is available on request
for customized parts.
