EFC Series 1213 are metallized polypropylene capacitors. This series offers the advantage of superior stability, self healing, high insulation resistance, low dissipation factor and high frequency operation.
1. TEMPERATURE RANGE
- 55 °C to + 85 °C at rated voltage.
To 105 OC with 25% voltage derating.
Capacitors < 1.0 MFD shall be measured at 1 KHz + 20 HZ. Capacitors >1.0 MFD shall be measured at 60 HZ. Measurements shall be taken at 25 OC.
3. DIELECTRIC STRENGTH
At 25 OC, 150% of rated voltage when applied terminal to terminal for one minute through a current limiting resistance.
4. INSULATION RESISTANCE
At 25 OC after 2 minutes charge time at rated voltage or 500 VDC, whichever is less, the minimum IR shall be 80,000 Megohm-Microfarads, but need not exceed 120,000 Megohms.
5. HUMIDITY RESISTANCE
Series 1213 shall meet the requirements of MIL-STD. 202C, Method 103B.
6. DISSIPATION FACTOR
Shall be 0.1 % max. when measured as in Par. 2.
7. LIFE TEST
Will withstand the application of 150% rated voltage at +85 0C for 250 hours
with not more than one failure in 12 permitted.
