B82767S4123N030

Overview

The B82767S4123N030 is a current-compensated ring core quad choke manufactured by EPCOS (TDK). It features four independent lines designed for common mode filtering applications. The component provides an inductance of 1.45 mH per line and supports a maximum current rating of 12 A. Its physical dimensions are limited to a maximum length and width of 60.00 mm, facilitating integration into compact power electronics designs.

Feature Summary

• Current-compensated ring core design for efficient magnetic field cancellation
• Quad choke configuration providing four independent filtering lines
• High current handling capability suitable for robust power conversion systems

Applications

• Power supplies requiring common mode noise suppression
• Battery charger circuits for signal integrity
• Portable electronic devices with strict EMC requirements

Procurement Notes

Verify the specific ordering code against official TDK Electronics documentation to ensure correct pinout and tolerance specifications. Confirm that the 12 A current rating aligns with your system's peak load requirements. Check for any recent product lifecycle updates or alternative package options available from authorized distributors.

Selection Notes

Select this component when high current capacity and multi-line filtering are required in a single footprint. The ring core construction offers superior performance compared to standard wire-wound chokes in high-current scenarios. Ensure the 60 mm maximum dimension fits within the designated PCB area and enclosure constraints.

Part Context

This component belongs to the B82767 series of common mode chokes from EPCOS, now part of TDK Electronics. The series is engineered for demanding industrial and consumer applications where reliable electromagnetic interference suppression is critical. The quad choke variant specifically addresses complex multi-phase or multi-circuit filtering needs.

Replacement Considerations

Consult official TDK cross-reference lists for verified substitutes. Ensure replacement parts maintain identical inductance values and current ratings to preserve circuit performance.
