CM6594R-253

Common Mode Chokes Overview

The Delevan CM6594R-253 is a surface-mount common mode filter choke designed for PCB integration. It features an unshielded ER core with four windings and offers an inductance of 25 uH with a 25% tolerance. The component supports a maximum DC current of 1 A and maintains a maximum DC resistance of 0.04 ohms. Physical dimensions are 0.465 inches in length, 0.405 inches in width, and 0.235 inches in height.

Common Mode Chokes Feature Summary

• Utilizes an unshielded ER core structure with four windings for effective noise suppression
• Designed for direct surface-mount technology (SMT) installation on printed circuit boards
• Provides standardized inductance values suitable for general-purpose filtering applications

Common Mode Chokes Applications

• Common mode noise filtering in electronic circuits
• Signal integrity enhancement in high-speed data lines
• Power supply input/output interference suppression

Common Mode Chokes Procurement Notes

Verify the specific RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates detailed requirements rather than a simple pass/fail label. Confirm that the ordering suffix matches the required reel quantity specifications to ensure compatibility with automated assembly equipment. Cross-reference the part number against the latest datasheet to validate electrical parameters before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a low-profile, unshielded common mode choke is required for SMT assembly processes. The 25 uH inductance value is appropriate for filtering lower frequency noise compared to higher inductance variants in the series. Ensure the 1 A current rating aligns with the operational DC current of the target circuit to prevent saturation. Consider the physical footprint constraints relative to the 0.465 x 0.405 inch package size during layout design.

Common Mode Chokes Part Context

This component belongs to the CM6594R series of common mode chokes manufactured by Delevan. The series is characterized by surface-mount packaging and ER core construction. Variants within the series differ primarily in inductance values and corresponding current ratings, allowing designers to scale filtering performance while maintaining consistent mechanical mounting profiles across different circuit designs.
