MIL-PRF-23648-1 Resistor, Thermal \(Thermistor\), Insulated Negative Temperature Coefficient Style Rth06This specification covers the performance requirements for style RTH06 thermistors. This style is available in resistance ratios A, B, and C. The only terminal lead available is S type. Resistance tolerance versus temperature characteristics F, G, J, and K are applicable through the maximum temperature of 125 degrees C.

3.6.2 Resistance at temperatures other than 25�C. Factors for determining resistance at temperatures

other than 25�C are determined by multiplying the zero-power resistance at 25�C by the factors shown in

table II for the applicable resistance ratio.
