Dscc (Defense Supply Center, Columbus) issued
specification 03017 in the Spring of 2003 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 criti-
cal space flight applications.
Quality Thermistor has summarized the requirements of the
03017 specification on this catalog page. The complete detailed
03017 specification can be obtained by contacting the DSCC.
The High-Rel 03017 Positive Temperature Coefficient
chip thermistor is designed for wire bonding appli-
cations found in hybrid circuitry. The devices exhibit
a linear Resistance vs. Temperature curve approxi-
mating 0.7%/C which make them the ideal solution
for temperature compensation applications.
Quality Thermistor, Inc. is
