METALLIZED POLYESTER
SERIES 1313
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).
SPECIFICATIONS
1. TEMPERATURE RANGE
- 55
O
C to + 85
O
C at rated voltage.
To 125
O
C at 50% derating.
4. INSULATION RESISTANCE
At 25
O
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.
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
O
C.
5. HUMIDITY RESISTANCE
Series 1313 shall meet the requirements
of MIL-STD. 202C, Method 103B.
3. DIELECTRIC STRENGTH
At 25

terminal to terminal for one minute through a
current limiting resistance.
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
0
C for 250 hours
with not more than one failure in 12 permitted.
