B82721A2501N001

Overview

The B82721A2501N001 is a current-compensated ring core double choke designed for power line applications. It features a ferrite core and polycarbonate case with polyurethane potting. The component provides an inductance of 18 mH at 10 kHz, with a maximum DC current rating of 500 mA. Its maximum DC resistance is typically 1.4 Ohms. The device supports through-hole mounting and operates within a temperature range of -40°C to +125°C.

Feature Summary

Current-compensated design ensures symmetrical interference suppression with low stray inductance.
High resonance frequency achieved through specialized sector winding techniques.
Flame-retardant construction compliant with UL 94 V-0 standards for safety.

Applications

Power line filtering in industrial electronics
EMI suppression in automotive systems
Common mode noise reduction in consumer appliances

Procurement Notes

Verify the specific suffix N001 against official EPCOS/TDK documentation to confirm pin configuration and packaging details. Ensure compatibility with required thermal management strategies given the 125°C operating limit. Cross-reference datasheet revisions to validate electrical parameters prior to integration.

Selection Notes

Select this component when 18 mH common mode attenuation is required at 500 mA. Consider the radial through-hole footprint for PCB layout constraints. Evaluate thermal performance under continuous load conditions to ensure operation remains within the specified ambient temperature range without derating.

Part Context

This part belongs to the B82721 series of current-compensated ring core chokes from EPCOS (TDK). The series utilizes ferrite cores for high permeability and stability. These components are engineered for robust electromagnetic compatibility in demanding environments, distinguishing them from standard shielded inductors by their differential mode efficiency.

Replacement Considerations

B82721A2501N22 offers similar specifications but may differ in tolerance or packaging. Verify inductance values and physical dimensions before substitution. Consult official cross-reference lists for confirmed equivalents.
