TABLE A: THERMAL AND ELECTRICAL PROPERTIES:
The following table lists the THERMAL and ELECTRICAL properties for all LARGE RUGGEDIZED THERMISTORS. All definitions and
test methods are per MIL-PRF-23648.
RESISTANCE -VS- TEMPERATURE CHARACTERISTICS: The nominal resistance range for the zero-power resistance at 25°C is shown
for each THERMISTOR Type and each available Material System. Each Material System is denoted by an ordering Code Letter,
a referenced Curve number and the nominal 25°C/125°C resistance ratio.
