 APPLICATION
The Type 6512-106R Feed-Thru Capacitor was especially designed
for use in RFI/EMI test setups as required by MIL-STD-461/462 and other specifications. In this application it provides a low r.f. impedance across the power source so that EMI currents produced by a test sample can be accurately measured with current probes.
The 10 µF feed-thru capacitor can also be used as a power line filter installed in the wall of a shielded enclosure or equipment cabinet.
The capacitor provides adequate insertion loss without suffering the power current saturation limitation
of conventional filters which employ toroidal inductors.
DESCRIPTION
The Type 6512-106R Feed-Thru Capacitor is a highly reliable and ruggedly constructed unit for general use in screen rooms or other environments. The 3.375" square case with four husky mounting inserts lends

itself to convenient installation with a minimum of effort. The 1⁄4-28 UNF threaded feed-thru stud will easily accommodate power currents in excess of 100 amperes without heating or voltage loss. The capacitance value is 10 µF ±10%. The
Type 6512-106R voltage rating is 600
volts d.c., 275 volts at 60 Hz, and 250 volts at 400 Hz. Low dissipation factor, high temperature rating, high insulation resistance, doubly rated dielectric strength, and long life characterize this versatile device. To satisfy safety requirements,
a bleeder resistance is included in the
Type 6512-106R Feed-Thru Capacitor which serves to discharge the capacitor when the applied voltage is removed.
FEATURES
- High insulation resistance over wide temperature range.
- Excellent stability with long life.
Built-in discharge resistor for safety.
- Designed for bulkhead or bench mounting.
SPECIFICATIONS
Capacitance: 10 microfarads.
Tolerance: ±10% at 25 C.
Voltage Rating:
600 volts d.c.
275 volts r.m.s. at 60 Hz.
250 volts r.m.s. at 400 Hz.

Current Rating: Limited by the heat
of the 1⁄4-28 threaded terminal stud. Easily handles 100 amperes of power current. Can be used for currents in excess of 200 amperes intermittent duty.
Temperature: Will operate at full rated voltage from -55 C to 100 C. To +125 C with 50% voltage derating.
Dissipation Factor: Less than 1%
at 25 C. Dielectric Strength: Will withstand the application of twice
rated voltage at 25 C for a period
not to exceed two minutes.
Insulation Resistance: At rated voltage or less for a period two minutes, the insulation resistance
will exceed 2500 megohms at 25 C. However, insulation in excess of 500,000 ohms cannot be measured due to the bleeder resistor built into the unit.
Bleeder Resistance: An internal bleeder resistor of 500,000 ohms is included as specified in SAE document ARP-936.
Life Test: Will withstand the application of 600 volts at 85 C
for 250 hour.
Construction: Extended foil coaxial winding protected with a thin mylar film. Hermetically sealed with ceramic to metal seals.
