B82722A2132N001

Overview

The B82722A2132N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a ferrite core and a polycarbonate case with polyurethane potting. The component has a rated inductance of 6.8 mH per winding, tested at 10 kHz. It supports a maximum DC current of 1.3 A and exhibits a maximum DC resistance of 0.23 Ω. Designed for through-hole mounting, it operates within a temperature range of -40 °C to +125 °C and complies with RoHS standards.

Feature Summary

• Current-compensated design utilizing a ferrite ring core for symmetrical interference suppression
• High resonance frequency achieved through specialized sector winding techniques
• Robust construction with UL 94 V-0 rated polycarbonate housing and polyurethane potting
• Compliant with EN 60938-2 standards and suitable for wave soldering processes

Applications

• Suppression of common-mode interferences in power lines
• Electronic ballasts in lighting systems
• Switch-mode power applications

Procurement Notes

Verify the specific suffix against official EPCOS documentation to confirm electrical characteristics, as variations exist within the B82722 series. Ensure the procurement specification matches the required inductance tolerance and current rating for the target circuit. Confirm RoHS compliance status and packaging format requirements prior to ordering to align with assembly line capabilities.

Selection Notes

Select this component for circuits requiring high common-mode rejection in power line filtering. The current-compensated architecture minimizes stray inductance, making it ideal for symmetric noise suppression. Consider the physical dimensions and through-hole mounting style when designing PCB layouts. Verify thermal management requirements given the operating temperature limits and self-heating under load conditions.

Part Context

This part belongs to the B82722 series of power line chokes from EPCOS. The series covers various inductance values ranging from 1.2 mH to 68 mH with rated currents from 0.3 A to 3 A. These components are widely used in industrial and consumer electronics for electromagnetic compatibility enhancement.

Replacement Considerations

Cross-reference with other B82722 variants such as B82722J2132N001 or B82722A2172N001 if different inductance or current ratings are needed. Ensure mechanical footprint compatibility for through-hole installation when substituting.
