MIL-PRF-23648F
3.15 Resistance temperature characteristics. When thermistors are tested as specified in 4.8.13, the
curve obtained for each thermistor shall conform to the curve specified (see 3.1) and fall within the
tolerance limits specified in table III (for the appropriate tolerance characteristic) at each of the
temperature points indicated in table III.
3.16 Thermal shock. When thermistors are tested as specified in 4.8.14, thermistors shall show no
evidence of mechanical damage. The change in zero power resistance shall not exceed the value
specified (see 3.1).
3.17 Resistance to soldering heat. When thermistors are tested as specified in 4.8.15, thermistors
shall show no evidence of mechanical damage. The change in zero power resistance shall not exceed
the value specified (see 3.1).
3.18 Moisture resistance. When thermistors are tested as specified in 4.8.16, thermistors shall show
no signs of electrical damage, breaking, cracking, or loosening of the terminals. The change in zero
power resistance shall not exceed the value specified (see 3.1). In addition, the insulation resistance
shall not be less than 100 megohms minimum (see 4.8.6).
3.19 Load life. When thermistors are tested as specified in 4.8.17, thermistors shall show no evidence
of corrosion or other mechanical damage. The change in zero power resistance shall not exceed the
value specified (see 3.1).
3.20 High temperature exposure. When thermistors are tested as specified in 4.8.18, the change in
zero power resistance after 100 hours, and after 1,000 hours shall not exceed the value specified (see
3.1).
3.21 Vibration, high frequency. When thermistors are tested as specified in 4.8.19, there shall be no
evidence of mechanical damage. The change in zero power resistance shall not exceed the value
specified (see 3.1).
3.22 Shock, specified pulse. When thermistors are tested as specified in 4.8.20, thermistors shall
show no evidence of mechanical damage and the change in zero power resistance shall not exceed the
value specified (see 3.1).
3.23 Immersion. When thermistors are tested as specified in 4.8.21, there shall be no evidence of
mechanical damage. The change in zero power resistance shall not exceed the value specified (see
3.24 Resistance to solvents. When thermistors are tested as specified in 4.8.22, there shall be no
evidence of mechanical damage and the marking shall remain legible.
3.25 Marking. Thermistors shall be marked with the PIN and the manufacturer's name, trademark, or
code symbol, in accordance with MIL-STD-1285. If lack of space requires it, packages only may be
marked. The following is a sample part marking:
