CM6594R-254

Overview

The Delevan CM6594R-254 is a surface-mount common mode choke featuring a four-wire ER core configuration. It provides an inductance of 250 uH with a tolerance of 25%. The component supports a maximum DC current of 500 mA and exhibits a maximum DC resistance of 0.13 ohms. Designed for PCB mounting, it utilizes SMD/SMT termination types to facilitate automated assembly processes.

Feature Summary

• Four-wire ER core construction for enhanced filtering performance
• Surface-mount design optimized for automated PCB assembly
• Common mode noise suppression capability

Applications

• Electromagnetic interference reduction in electronic circuits
• Signal integrity protection in high-speed data lines
• Power supply input filtering applications

Procurement Notes

Verify the manufacturer designation as API Delevan or Delevan during sourcing. Confirm RoHS compliance status and lead time requirements directly with authorized distributors. Ensure the specific reel quantity matches production needs. Validate that the four-wire configuration aligns with the target circuit schematic before finalizing orders.

Selection Notes

Select this component when a 250 uH inductance value is required for common mode noise attenuation. The 500 mA current rating suits moderate power applications. The four-wire topology offers distinct advantages over standard two-wire chokes in specific differential signal environments. Verify physical footprint compatibility with existing PCB layouts.

Part Context

This part belongs to the CM6594R series of common mode filter chokes manufactured by Delevan. The series typically features ER cores and surface-mount packaging. Other variants in the family include different inductance values such as 150 uH or 100 uH, sharing similar mechanical dimensions and mounting styles.

Replacement Considerations

Cross-reference with other API Delevan CM6594R series parts for alternative inductance values. Verify pinout compatibility if substituting with components from different manufacturers. Ensure equivalent current handling and impedance characteristics are maintained.
