CM6149R-474

Overview

The Delevan CM6149R-474 is a surface-mount common mode choke filter designed for PCB integration. It provides an inductance of 470 µH with a tolerance of -25% to +35%. The component supports a maximum DC current of 1.5 A and exhibits a maximum DC resistance of 60 mOhms. Its physical dimensions are 9.14 mm in length, 9.14 mm in width, and 5.08 mm in height. The device operates within a temperature range of -55°C to +105°C and is classified as unshielded.

Feature Summary

• Surface mount construction for automated PCB assembly
• Unshielded core design for standard EMI suppression
• Low profile form factor suitable for space-constrained layouts

Applications

• Common mode noise filtering in electronic circuits
• EMI suppression in signal lines
• Power supply input filtering

Procurement Notes

Verify the specific suffix or packaging designation when ordering, as availability may vary between cut tape, reel, or bulk formats. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions. Ensure the selected variant matches the required inductance tolerance and current rating specifications for the target application.

Selection Notes

Select this component based on the required 470 µH inductance value and the 1.5 A current handling capability. Evaluate the 60 mOhms DC resistance against circuit loss requirements. Consider the 9.14 mm x 9.14 mm footprint and 5.08 mm height constraints during PCB layout planning. Verify thermal performance at the intended operating temperature range up to 105°C.

Part Context

This part belongs to the Delevan CM6149R series of common mode chokes. The series offers various inductance values tailored for different filtering needs while maintaining consistent surface-mount package dimensions. These components are engineered for reliable performance in industrial and commercial electronic equipment requiring effective electromagnetic interference mitigation.

Replacement Considerations

Cross-reference with other Delevan CM6149R variants such as CM6149R-224 or CM6149R-154 if different inductance levels are acceptable. Verify that substitute parts maintain compatible physical dimensions and electrical characteristics including current rating and DC resistance.
