B82724A2142N021

Overview

The B82724A2142N021 is a current-compensated ring core double choke from the EPCOS (TDK) B82724 series. It features a ferrite core and radial leads for through-hole mounting. The component has an inductance of 37 mH per winding, rated for a maximum DC current of 1.4 A at +60 °C ambient temperature. It supports AC voltages up to 250 V and operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Current-compensated design utilizing a ring core structure
• Dual-winding configuration for power line filtering
• Radial leaded construction for through-hole integration

Applications

• Power line chokes
• Common mode noise suppression
• Electromagnetic compatibility filtering

Procurement Notes

Verify the specific thermal rating (+60 °C) against system requirements, as this variant differs from other temperatures in the B82724 family. Confirm that the 1.4 A current rating aligns with the application's peak load. Ensure the radial package dimensions fit the PCB layout constraints.

Selection Notes

Select this part when a high-inductance common mode choke is required for power lines. The +60 °C rating indicates suitability for environments where ambient heat may affect performance. Compare against the B82724J or K series if different current or temperature ratings are needed.

Part Context

This component belongs to the B82724 series of power line chokes manufactured by EPCOS, now part of TDK Electronics. These components are designed for general-purpose electromagnetic interference suppression in AC power applications, offering robust performance in industrial and consumer electronics.

Replacement Considerations

Check for equivalents within the B82724 series such as B82724A2142N001 or variants with different thermal ratings like B82724J2402N1. Verify that substitute parts match the 37 mH inductance and 1.4 A current specifications.
