This is a current-compensated ring core double choke from TDK's B82721A series, designed for power line common-mode interference suppression. It features a ferrite core with epoxy coating, plastic case, and potting, all meeting UL 94 V-0 flammability rating.
Key electrical specifications include 700 µH inductance (measured at 100 kHz, ±30% tolerance), 4 A rated current (derated at elevated temperatures up to +70°C), 250 V AC rated voltage, and maximum DC resistance of 30 mOhm. The stray inductance is approximately 1% of rated inductance for symmetrical interference suppression.
The component is housed in a horizontal through-hole package with 4 PC pins (0.7 x 0.7 mm) and lead spacing options of 10 x 5 mm or 10 x 15 mm. Dimensions are 17.90 mm length, 17.30 mm width, and 13.40 mm height. Operating temperature range is -40°C to +125°C.
Applications include switch-mode power supplies, electronic ballasts, and power inverters. The choke is RoHS-compatible and has approvals from ENEC, UR, and VDE. It is delivered in blister trays in cardboard boxes.
