B82731M2132A030

Overview

The B82731M2132A030 is a common mode choke from the EPCOS B82731 series, designed for power line applications. It features a ferrite core and radial through-hole termination. Key electrical parameters include an inductance of 6.8 mH and a rated current of 1.3 A. The maximum AC voltage rating is 250 V, with a typical DC resistance of 280 mOhm per line. The component operates within a temperature range of -40 to +125 °C, including self-temperature rise.

Feature Summary

• Provides common mode noise suppression for dual-line power circuits
• Utilizes a ferrite core structure for effective high-frequency attenuation
• Designed for robust performance under significant self-heating conditions

Applications

• Power line chokes for electronic equipment
• EMI filtering in industrial electronics
• Noise suppression in automotive power supplies

Procurement Notes

Verify the specific suffix 'A030' against the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance details. Ensure the ordering code matches the required inductance tolerance and current rating specifications for your design. Cross-reference the package dimensions and pin spacing with your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a 6.8 mH common mode inductance is required for 250 V AC applications. The 1.3 A current rating suits moderate power loads. Consider the -40 to +125 °C operating range for environments with thermal stress. Verify that the radial through-hole format fits the assembly process constraints compared to surface-mount alternatives.

Part Context

This part belongs to the EPCOS B82731 series of power line chokes. These components are manufactured by EPCOS, now part of TDK Electronics. The series focuses on current-compensated E-core double chokes for suppressing electromagnetic interference in AC power lines. They are widely used in consumer, industrial, and automotive sectors for compliance with emission standards.

Replacement Considerations

Check for direct substitutes within the B82731 series with different inductance values if 6.8 mH is not critical. Verify mechanical compatibility with other radial chokes from TDK or competitors. Ensure replacement parts meet the same 250 V AC and 1.3 A ratings.
