MIL-PRF-83530C
e.
Pulse polarity - Shall alternate as a minimum after every 50 pulses.
f.
Measurements after test - Nominal voltage and clamping voltage shall be measured as specified in 4.8.2 and
4.8.3 respectively.
g.
Examination after test - Resistors shall be examined for evidence of mechanical damage.
4.8.7 Energy (see 3.12). 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 - 10 x 1,000 μs (see 6.5.2).
b.
c.
Pulse repetition rate - A single pulse only shall be applied.
d.
Pulse polarity - Not specified.
e.
Procedure:
Verify that the peak current is within tolerance and that the pulse energy level is as specified (see 3.1).
(1)
(2)
Pulse energy (E) can be estimated by the following:
E = 1.4 Vc Ip γ
Where:
Vc = Clamping voltage
Ip = Peak current
γ
= Impulse duration see figure 1
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.
4.8.8 Dielectric withstanding voltage (see 3.13). Resistors shall be tested in accordance with method 301 of
MIL-STD-202. The following details and exceptions shall apply:
a.
Test voltage - 2,500 V dc.
b.
Duration - 60, -0, +5 seconds.
c.
Point of application - The resistor body shall be immersed to the leads into a container of conductive shot.
The shot diameter shall not exceed .032 inch (0.8 mm). One test terminal shall be applied to the conductive
shot. The other test terminal shall be applied to the resistor leads which shall be connected together by a
jumper wire.
d.
Current - 1 mA ±20%.
e.
Examination after test - Resistors shall be examined for evidence of flash-over, mechanical damage, arcing,
and insulation breakdown.
