CM6149-154

Overview

The Delevan CM6149-154 is a surface-mount common mode choke designed for PCB integration. It features an unshielded construction with a low-profile form factor measuring 7.24 mm in length and width, and 5.08 mm in height. The component provides an inductance of 150 µH at 10 kHz with a tolerance range of -25% to +35%. It supports a maximum DC current of 1.3 A and exhibits a maximum DC resistance of 40 mΩ. The device operates within a temperature range of -55°C to +105°C and utilizes SMD/SMT termination for reliable board mounting.

Feature Summary

• Surface-mount design optimized for automated PCB assembly processes
• Unshielded magnetic structure suitable for standard EMI suppression applications
• Low-profile physical dimensions facilitating compact electronic enclosure layouts

Applications

• Common mode noise filtering in high-frequency signal lines
• EMI suppression in data communication interfaces
• Power line filtering in consumer electronics assemblies

Procurement Notes

Verify the specific suffix designation (e.g., R100, B100) against the required packaging format, as bulk or reel options may affect handling procedures. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions. Ensure that the selected variant matches the exact inductance and current rating requirements of the target circuit design to prevent performance deviations.

Selection Notes

Select this component when a 150 µH inductance value is required for common mode noise reduction in space-constrained designs. The 1.3 A current rating defines the operational limit for continuous DC bias conditions. Consider the unshielded nature of the device regarding potential magnetic coupling with adjacent components. Verify that the 40 mΩ DCR aligns with the voltage drop constraints of the application circuit.

Part Context

This part belongs to the CM6149 series of common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering requirements while maintaining consistent physical footprints. The CM6149-154 specifically addresses applications requiring moderate inductance levels with robust current handling capabilities in a small surface-mount package.

Replacement Considerations

Direct substitutes include other CM6149 series variants such as CM6149-104 or CM6149R-154, provided the inductance and current ratings match the design specifications. Cross-referencing pinout compatibility and physical dimensions is essential when considering alternative manufacturers' components.
