CM6149-225

Overview

The Delevan CM6149-225 is a surface-mount common mode choke filter designed for PCB integration. It features an inductance of 2.2 mH at 10 kHz with a tolerance of 25%. The component supports a maximum DC current rating of 180 mA and exhibits a maximum DC resistance of 750 mOhms. Physical dimensions are 7.24 mm in length, 7.24 mm in width, and 5.33 mm in height. It operates within a temperature range of -55°C to +105°C.

Feature Summary

• Provides common mode noise suppression via dual-line filtering architecture
• Utilizes a low-profile horizontal surface mount package for space-constrained designs
• Constructed as an unshielded component suitable for general electromagnetic interference mitigation

Applications

• Signal line filtering in electronic circuits
• Noise reduction in data transmission interfaces
• Electromagnetic interference suppression in compact devices

Procurement Notes

Verify the specific suffix designation (e.g., BULK) against the required packaging format, as availability varies by reel or bulk configuration. Confirm that the 180 mA current rating aligns with the target circuit's operational requirements. Ensure the 750 mOhm DC resistance does not introduce excessive voltage drop in the application path.

Selection Notes

Select this component when a 2.2 mH inductance value is required for common mode noise attenuation. The 180 mA current limit dictates suitability for low-power signal lines rather than high-current power rails. The 5.33 mm height profile allows for use in thin enclosures where vertical clearance is restricted.

Part Context

This part belongs to the CM6149 series of surface-mount common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering needs while maintaining consistent physical footprints. These components are categorized under inductors, chokes, and coils within passive component classifications.

Replacement Considerations

Cross-reference with other CM6149 series variants such as CM6149-104 or CM6149R-154 if different inductance levels are needed. Verify that substitute parts maintain compatible current ratings and physical dimensions to ensure board compatibility.
