B82733V2142B001

Overview

The B82733V2142B001 is a current-compensated frame core double choke manufactured by EPCOS (TDK). It features a closed magnetic circuit with a ferrite frame construction and a PET coil former rated UL94 V-0. The component utilizes a 4-section winding directly on the core, ensuring clearance and creepage distances greater than 3 mm. Designed for power line applications, it operates at a rated voltage of 250 V AC and supports rated currents ranging from 0.7 to 2.3 A at +40 °C. The inductance range spans 10 to 100 mH.
