MIL-PRF-83530C
4.8.5 Peak current (see 3.10). Resistors shall be tested in accordance with method 4141 of MIL-STD-750. The
following details and exceptions shall apply:
a.
Pulse generator source impedance and pulse voltage - Shall be such as to supply the specified peak current
value ±10% (see 3.1).
Pulse width - An impulse waveform of 8 x 20μs (see 6.5.2).
b.
c.
Pulse repetition rate - A single pulse only shall be applied.
d.
Polarity of pulse - Not specified.
e.
Procedure:
(1). Verify the test set-up and that the peak current is within tolerance.
(2). Test the inspection lot to verify their capability to withstand the peak current value.
(3). When peak current is applied, clamping voltage shall be measured as specified in 4.8.3 and herein.
(a). The measuring instrument shall employ voltage probes separate from the current conducting
connections.
(b). The probes shall contact the resistor leads no greater than 0.3 inch (7.6 mm) from the resistor
body.
Measurements after test - Nominal voltage and clamping voltage shall be measured as specified in 4.8.2 and
f.
4.8.3 respectively.
g.
Examination after test - Resistors shall be examined for evidence of mechanical damage.
4.8.6 Pulse life (see 3.11). Resistors shall be tested in accordance with method 4141 of MIL-STD-750. The
following details and exceptions shall apply:
a.
Pulse generator source impedance and pulse voltage - Shall be such as to supply the specified current value
±10% (see 3.1).
Pulse width - 8 x 20 μs (see 6.5.2).
b.
c.
Pulse repetition rate - Maximum pulse repetition rate shall be such that the theoretical pulse energy
absorbed by the device is dissipated at 90% of the value of the transient average power dissipation, Wtm
±10% (see 3.1) and shall be computed by the following formula:
PRR = .9 Wtm/Vc Ip x 2 x 10-5
Where:
d.
Test duration - A minimum of 10,000 pulses shall be applied.
