CLR 81 (MIL-C-39006/25)

Performance Testing

Seal: MIL-STD-202 - Method 112

•

Conditions A, or D, and C

Specified Pulse Shock Test: MIL-STD-202 - Method 213 includes the following:

•

Condition D (500g’s)

•

Mount the capacitor by its body securely on a fixture taking special care not to squeeze the leads.

•

While testing apply DC rated voltage. Record whether open or short circuiting, arching, or intermittent contact

occurs. Use detecting equipment capable of detecting a disruption at a period of time up to 0.5 ms.

•

At the conclusion of testing examine the capacitors for evidence of arcing, breakdown, or mechanical damage.

Thermal Shock: MIL-STD-202 – Method 107, Condition A (with step 3 at +125°C)

In accordance with MIL-PRF-39006, the following shall apply:.

•

Take measurements before and after cycling.

•

Take measurements at 15-minute intervals at 300 cycles (Group C).

•

Take final measurements at room temperature.

High Frequency Vibration: MIL-STD-202 - Method 204 includes the following:

•

Condition H (80g’s)

•

Mount the capacitor body securely on a fixture with the leads firmly supported.

•

Apply DC rated voltage while measuring specific electrical load conditions.

•

The vibration duration is 4 hours in two perpendicular directions for an overall time of 8 hours.

•

Take measurements during the last cycle vibration to determine open, short-circuiting or intermittent operation.

Use detecting equipment capable of detecting a disruption at a period of time of 0.5ms or greater. Assess the

units for mechanical damage and test for these electrical requirements:.

o DC Leakage — Not greater than 1.25 initial limit

o Capacitance — No change greater than ±5% of the initial limit

o DF — Not greater than 1.15 of initial limit

Random Vibration: MIL-STD-202 – Method 214

•

Test condition II-K (51 g’s)

Salt atmosphere: MIL-STD-202 – Method 101

•

Condition B 48 hours

Solderability: MIL-STD-202 – Method 208

•

Test both terminations with the insertion depth of flux and solder within .062" of welded seam.

Lead Terminal Strength:

•

Pull Test: MIL-STD-202 – Method 211, condition A

•

Wire-lead bend: Per MIL-PRF-39006.

•

During the test securely clamp the capacitor body. Apply a force of 3 pounds or 1.4 kg for 30 seconds.

Moisture resistance: MIL-STD-202- Method 106, which includes the following:

•

Mount the capacitor body securely on a fixture taking special care not to squeeze the leads.

•

Apply 6 volts, polarizing and load voltage

•

At the time of the capacitors complete their final cycle remove them from the humidity chamber and measure per

MIL-PRF-30006 for DC Leakage, dissipation factor, and capacitance.

o DCL: 125% (Maximum) of +25°C value of standard ratings table

o ∆Cap: Within ±8% of initial measurement

o DF: 115% (maximum) of initial requirement
