EFC Series 1313 are metallized polyester capacitors. This series offers the advantage of small size, self healing and low cost. Suggested applications include: medical electronics, telecommunications and high voltage power supplies. Packaging options include: wrap and fill (TF, TC), radial lead box (EFR), axial lead (EC, EF). Application options include: high voltage (HV), "AC" across the line (AC), noise suppression (RC) and switching power supply (SP). 1. TEMPERATURE RANGE - 55 °C to + 85 °C at rated voltage. To 125 °C at 50% derating. 2. CAPACITANCE Capacitors < 1.0 MFD shall be measured at 1 KHz + 20 HZ. Capacitors >1.0 MFD shall be measured at 120 HZ. Measurements shall be taken at 25 °C. 3. DIELECTRIC STRENGTH At 25 °C, 150% of rated voltage when applied terminal to terminal for one minute through a current limiting resistance. 4. INSULATION RESISTANCE At 25 °C after 2 minutes charge time at rated voltage or 500 VDC, whichever is less, the minimum IR shall be 30,000 Megohm-Microfarad, but need not exceed 50,000 Megohms for voltages greater than 50 VDC, and 15,000 Megohm-Microfarads, but need not exceed 30,000 Megohms for 50 VDC or less. 5. HUMIDITY RESISTANCE Series 1313 shall meet the requirements of MIL-STD. 202C, Method 103B. 6. DISSIPATION FACTOR Shall be 1.0 % max. when measured as in Par. 2. 7. LIFE TEST Will withstand the application of 150% rated voltage at +125 °C for 250 hours with not more than one failure in 12 permitted.
