B82731H2112A030

Overview

The B82731H2112A030 is a current-compensated double choke manufactured by EPCOS (TDK). It functions as a single-phase EMI filter with a rated voltage of 250 V AC and operates at frequencies of 50/60 Hz. The component features a nominal inductance of 10 mH per line and supports a rated current of 1.1 A. Its physical dimensions are 21 mm in length, 15 mm in width, and 20 mm in height. The device utilizes through-hole mounting and has tin-plated terminals with a nickel barrier.

Feature Summary

Provides electromagnetic interference suppression for single-phase circuits
Utilizes current-compensated double choke construction
Designed for through-hole board mounting

Applications

Single-phase power supply input filtering
Electromagnetic compatibility enhancement in electronic devices
Noise reduction in 50/60 Hz AC mains applications

Procurement Notes

Verify the specific part number suffix against official TDK documentation to confirm exact electrical characteristics and packaging details. Ensure that the selected variant matches the required inductance and current ratings for the target application. Cross-reference certification marks such as UL, IEC, VDE, and ENEC-10 with the manufacturer's datasheet to confirm compliance with regional safety standards before procurement.

Selection Notes

Select this component based on its 10 mH inductance and 1.1 A current rating suitability for single-phase EMI filtering. Consider the through-hole mounting requirement and physical dimensions of 21x15x20 mm for PCB layout constraints. Verify that the 250 V AC rating aligns with the system's operating voltage and that the 50/60 Hz frequency range meets the application's needs.

Part Context

This component belongs to the B82731 series of common mode chokes from EPCOS (TDK). The series includes various inductance and current ratings tailored for different EMI suppression requirements. These components are widely used in industrial and consumer electronics to meet regulatory emissions standards.

Replacement Considerations

Consult official TDK substitution guides for verified alternatives. Ensure any replacement maintains equivalent inductance, current handling, and physical footprint specifications.
