Military Grade PTC Chip Thermistor, MIL-PRF-32192/1

The High-Rel M32192/1 Positive Temperature Coefficient chip thermistor is designed for wire bonding applications found in hybrid circuitry. The devices exhibit a linear Resistance vs. Temperature curve approximating 0.7%/C which make them the ideal solution for temperature compensation applications.

DSCC (Defense Supply Center, Columbus) issued specification MIL-PRF-32192/1 in the Summer of 2005 which dictates the performance and inspection requirements for these devices which includes a test for wire bonding integrity. Many leading Aerospace companies around the world have selected these components for their mission critical space flight applications.
