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.
