B82731M2801A030

Overview

The B82731M2801A030 is a current-compensated double choke from the EPCOS B82731 series, designed for power line applications. It features a nominal inductance of 22 mH and a rated current of 800 mA. The component supports a rated voltage of 250 V AC and operates at temperatures up to +40 °C. Constructed with a D core, this through-hole device provides effective electromagnetic interference suppression in single-phase circuits.

Feature Summary

• Current-compensated design for efficient magnetic flux cancellation
• D core construction for compact form factor
• Through-hole termination style for robust PCB mounting

Applications

• Power line chokes for single-phase equipment
• Electromagnetic interference (EMI) suppression
• Input filtering in AC power supplies

Procurement Notes

Verify the specific ordering suffix against the official TDK Electronics datasheet to confirm exact electrical tolerances and packaging details. Ensure the component meets the required thermal class and voltage ratings for the target application environment before finalizing procurement.

Selection Notes

Select this component when a current-compensated choke with 22 mH inductance is required for 250 V AC lines. Consider the 800 mA rated current limit and +40 °C operating temperature constraint during circuit design to ensure reliable performance under load.

Part Context

This part belongs to the B82731 series of current-compensated double chokes manufactured by EPCOS, now part of the TDK Group. These components are engineered for general-purpose power line filtering, offering high common-mode impedance while maintaining low differential mode inductance.

Replacement Considerations

Consult the official B82731 series documentation for cross-reference data. Verify that any substitute maintains identical inductance, current rating, and physical dimensions to ensure compatibility with existing board layouts and regulatory certifications.
