B82731M2112A030

Overview

The B82731M2112A030 is a single-phase EMI filter and power line common mode choke manufactured by EPCOS (TDK). It features a rated AC voltage of 250 V and operates at frequencies of 50/60 Hz. The component has a nominal inductance of 2 x 10 mH with a maximum DC resistance of 400 mOhm. It supports a rated current of 1.1 A and functions within an operating temperature range of -40 to 125°C. The physical dimensions are 21 mm length, 15 mm width, and 20 mm height. It utilizes through-hole mounting with tin-plated terminals.

Feature Summary

Provides electromagnetic interference suppression for single-phase power lines
Constructed as a current-compensated double choke for common mode noise reduction
Designed for through-hole board mounting applications

Applications

Single-phase power supply input filtering
Electromagnetic compatibility enhancement in electronic equipment
