Insulation resistance: Not less than 10 megohms at room ambient temperature and not less than 10 megohms
at +125°C.
Test condition - 250 volts ±10 percent.
Quality factor (Q): See table I (measured at frequency of 100 MHz).
Driving torque: Greater than or equal to 0.3 ounce-inches and less than or equal to 4.0 ounce-inches from -55°C
through +125°C.
Thermal shock: Method 107 of MIL-STD-202, test condition A, except step 3 temperature shall be +125° ±5°C.
Immersion: Method 104 of MIL-STD-202, test condition A.
Resistance to soldering heat: Applicable to style PC28 and PC29 only.
Seal: Applicable, with seal cap on.
Qualification inspection: Qualification inspection is not required. A manufacturer that is currently listed on the QPL
for at least one other MIL-PRF-14409 style may supply PC27, PC28, and PC29 parts by performing the group A
and group B testing. A manufacturer that is not qualified to any MIL-PRF-14409 styles may produce these parts by
performing the group A, group B, and group C testing on the product before delivery.
