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.
