8 / 28 page  © KEMET Electronics Corporation, P.O. Box 5928, Greenville, SC 29606 (864) 963-6300 c. Test condition letter - H (80G). d. Duration and direction of motion - 4 hours in each of two mutually perpendicular directions (total of 8 hours), one parallel and the other perpendicular to the axis. e. Measurements during vibration - During the last cycle, an electrical measurement shall be made to determine intermittent operation or open- or short-circuiting. Observations shall also be made to determine intermittent con- tact or arcing or open- or short-circuiting. Detecting equipment shall be sufficiently sen- sitive to detect any interruption with a duration of 0.5 ms, or greater. • DC Leakage - shall not exceed 1.25 times initial limit • Capacitance - shall not change more than ± 5% from initial limit • DF - shall not exceed 1.15 times initial limit f. Examination after test - Capacitors shall be visually examined for evidence of mechanical damage. • Shock Test: Per MIL-STD-202, Method 213. The following details shall apply: a. Special mounting means - Capacitors shall be rigidly mounted on a mounting fixture by the body. When securing leads, care shall be taken to avoid pinching the heads. b. Test-condition letter - D (500 G peak). 6 ms. (sawtooth) c. Measurements and electrical loading during shock - During the test, observations shall be made to determine intermittent contact or arc- ing or open- or short-circuiting. Detecting equipment shall be sufficiently sensitive to detect any interruption with a duration of 0.5 ms. The DC rated voltage shall be applied to the capacitors during the test. d. Examinations after test - Capacitors shall be visually examined for evidence of arcing, breakdown, and mechanical damage. • Thermal Shock - MIL-STD-202, Method 107: Capacitors shall be subjected to thermal shock in accordance with MIL-STD-202, Method 107, Test Condition A except step 3 shall be +125°C. Measurements before and after cycling are required. Conditioning prior to the first cycle will be 15 minutes at the following standard inspec- tion conditions: a. Number of Cycles: 300 for qualification and Group C b. Ambient Temperature – 25°C ±5°C c. Final measurements are made after stabi- lization at room temperature • Moisture Resistance - MIL-STD-202, Method 106: Capacitors shall be tested in accordance with MIL-STD-202, Method 106 including the following details: a. Mounting - The capacitors shall be mounted by normal mounting means b. Initial Measurements c. Polarizing and Load Voltage - 6 vdc d. Final measurements - After the final cycle and within 2 to 6 hours after removal of the capacitors from the humidity chamber, capa- citance, dissipation factor, and DC leakage will be measured per MIL-PRF-39006. • Resistance to Solvents - MIL-STD-202, Method 215: a. Brushing required after test b. DCL meets limit shown in respective Part Number Tables c. Capacitance meets applicable tolerance d. DF meets limits shown in respective Part Number Tables e. No visible damage to case or marking • Resistance to Soldering Heat - MIL-STD- 202, Method 210, Test Condition, Letter C. Leads shall be immersed to within 0.05 inch of the capacitor body. Capacitance, DF, and DCL should meet original limits shown in respective Part Number Tables. • Solderability - MIL-STD, Method 208: a. Number of terminations on each capacitor tested: 2 b. Depth of insertion in flux and solder to with- in 0.062” of welded joint • Stability at Low and High Temperature -55°C to 125°C: Capacitors will be capable of withstanding extreme temperature testing at a succession of continuous steps at +25°C, -55°C, +25°C, +85°C, +125°C, +25°C, in the order stated. Capacitors shall be brought to thermal stability at each test temperature. Capacitance, DF, and DCL are measured at each test temperature except that DCL is not measured at -55°C, DC bias of 2.0 ±0.5 vdc is recommended for the capacitance and DF measurements. When measurements are made at the various steps, the electrical limits for each temperature shall not exceed the following limits. Step 1, +25°C DCL as indicated in original limit; capacitance within toler- ance specified; DF as indicat- ed in original limit shown in Part Number Tables. Step 2, -55°C Impedance and capacitance change as defined in M39006 Slash Sheet. 8 |
