Features

Why the CFT-10u is Essential for Your EMC Setup

10 microfarad Feed-Through Capacitor for MIL-STD-461 and RTCA DO-160 conducted emissions test setups — providing a stable, low RF impedance path across the power source for accurate current probe measurements.

MIL-STD-461 and RTCA DO-160 Compliant

Meets ARP936 insertion loss requirements per the MIL-STD-220 measurement method, making it a direct fit for MIL-STD-461 and RTCA DO-160 conducted emissions test setups.

100A Continuous Current at 40°C

Handles 100 amperes of continuous current at 40°C with no significant heating or voltage loss — ensuring uninterrupted test cycles throughout long compliance campaigns.

250 VAC / 600 VDC Rated, 10 µF ±10%

Rated for 250 VAC (50–400 Hz) and 600 VDC operation with 10 µF ±10% capacitance — covering a wide range of power supply configurations found in military and aerospace test environments.

Built-In 1.5 MΩ Bleeder Resistor for Operator Safety

The integrated 1.5 MΩ ±5% bleeder resistor safely discharges stored energy upon power-off, protecting laboratory personnel from electrical shock hazards during daily use.

Low RF Impedance for Accurate Current Probe Measurement

Provides the low RF impedance path across the power source required for current probes to capture true device emissions without measurement ambiguity caused by power supply impedance variations.

High Insulation Resistance — 100 MΩ

100 MΩ insulation resistance (prior to bleeder) with less than 1% dissipation factor at 25°C (120 Hz) — maintains excellent stability and long service life under continuous test-lab conditions.

Rugged CRCA Brass / Nickel-Plated Construction

CRCA brass and nickel-plated chassis with UL94 V-0 rated insulating material — built to withstand demanding test cycles across an operating temperature range of -55°C to +70°C at rated voltage.

Bulkhead or Bench Mounting via M4 Threaded Holes

Four M4 threaded mounting holes allow direct installation on shielded enclosure walls (bulkhead mount) or bench-top fixture plates — flexible deployment for both fixed lab installations and portable test setups.
