POLYPROPYLENE SNUBBER
SERIES MF1206
EFC Series MF1206 are polypropylene capacitors with an internal series construction of double-sided
metallized carrier and foil contact plates. This series offers the advantages of a self-healing metallized
dielectric and the high current/pulsing capabilities (see dv/dt Table) of a foil capacitor. Packaging
options include: wrap and fill (TC, TF), radial lead box (EFR), and radial lead dip (DFR).
SPECIFICATIONS
1. TEMPERATURE RANGE
-55°C to +85°C at rated voltage.
To 105°C with 25% voltage derating.
6. DISSIPATION FACTOR
Shall be 0.1% max. when measured at 25°C at 1 kHz.
2. CAPACITANCE
Measured at 25°C at 1 kHz.
7. LIFE TEST
Will withstand the application of 140% rated voltage at
+85°C for 250 hours with not more than one failure in
12 permitted.
3. DIELECTRIC STRENGTH
At 25°C, 160% of rated voltage for 10 seconds.

4. INSULATION RESISTANCE
At 25°C with maximum 2 minutes charge at rated
voltage or 500 VDC, whichever is less, the minimum
IR shall be 200,000 Megohm-Microfarads, but need
not exceed 250,000 Megohms.
5. HUMIDITY RESISTANCE
Series MF1206 shall meet the requirements
of MIL-STD. 202C, Method 103B.
