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
