B82724B2182N021

Overview

The B82724B2182N021 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It functions as a common mode choke with an inductance of 33 mH and a maximum DC current rating of 1.8 A. The component features radial termination for through-hole mounting and utilizes a ferrite core material. Its electrical specifications include a maximum DC resistance of 0.15 Ohms. The device is designed to operate within a temperature range of -40 °C to +125 °C, ensuring reliability in power line filtering applications.

Feature Summary

• Provides effective common mode noise suppression through current-compensated ring core design
• Utilizes ferrite core material for stable magnetic performance across operating temperatures
• Supports through-hole mounting via radial leads for secure PCB integration

Applications

• Power line filtering in industrial equipment
• Electromagnetic interference suppression in AC/DC converters
• Noise reduction in general purpose power supplies

Procurement Notes

Verify the manufacturer designation on the component body and datasheet, as TDK Electronics has transitioned from the EPCOS brand for passive components. Confirm that the specific suffix N021 corresponds to the required packaging and terminal configuration. Ensure compatibility with existing board layouts regarding lead spacing and mounting height constraints before finalizing procurement orders.

Selection Notes

Select this component when a high inductance value of 33 mH is required for common mode noise attenuation at currents up to 1.8 A. The radial through-hole package is suitable for applications requiring robust mechanical stability. Consider the 0.15 Ohm DC resistance for voltage drop calculations in the power path. Verify that the operating environment stays within the specified -40 °C to +125 °C temperature range for optimal performance.

Part Context

This component belongs to the B82724 series of current-compensated ring core double chokes. These chokes are engineered for power line applications where common mode interference needs to be minimized. The series offers various inductance values and current ratings to suit different power supply designs. As part of the TDK Electronics portfolio, these components adhere to strict quality standards for electronic passive elements.

Replacement Considerations

Check for direct substitutes within the B82724 series that match the 33 mH inductance and 1.8 A current rating. Verify pinout compatibility and physical dimensions if replacing with components from other manufacturers. Note that branding changes from EPCOS to TDK may affect ordering codes but not the underlying component specifications.
