B82731H2132A030

Overview

The B82731H2132A030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It features a ferrite core and operates at a rated voltage of 250 V AC. The component provides an inductance of 47 mH with a tolerance of ±20%. It has a maximum rated current of 0.9 A and a DC resistance of 0.6 Ω. Designed for power line applications, it supports a temperature range from -40 °C to +125 °C.

Feature Summary

• Dual-element design for effective noise suppression in power lines
• Current-compensated operation for stable performance under load
• D-core ferrite construction for high magnetic efficiency

Applications

• Power line chokes
• EMI filtering in industrial equipment
• Noise suppression in AC power circuits

Procurement Notes

Verify the specific suffix 'A030' against official TDK documentation to confirm pin configuration and packaging details. Ensure the application environment stays within the specified -40 °C to +125 °C operating range. Confirm that the required inductance and current ratings match the system design before procurement.

Selection Notes

Select this component when dual-channel noise suppression is required for AC power lines up to 250 V. The current-compensated design makes it suitable for applications where common-mode noise needs attenuation without affecting differential signals. Consider the physical size and mounting requirements for the rectangular package.

Part Context

This part belongs to the B82731 series of power line chokes from EPCOS, now integrated into TDK Electronics. The series is designed for robust electromagnetic interference suppression in various electronic systems. The D-core double choke configuration offers a compact solution for high-performance filtering in space-constrained applications.

Replacement Considerations

Check for direct substitutes within the B82731M/H series. Verify compatibility of inductance, current rating, and physical dimensions before replacing.
