Overview
The Delevan CM6149-334 is a surface-mount common mode filter choke designed for PCB integration. It features an inductance of 330 µH with a tolerance of 25%. The component supports a maximum DC current of 750 mA and exhibits a maximum DC resistance of 90 mΩ. Its physical dimensions are 7.24 mm in length, 7.24 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
- Provides common mode noise suppression through dual-line filtering architecture
- Utilizes a low-profile surface mount form factor for compact circuit board layouts
- Constructed with unshielded design characteristics suitable for general EMI mitigation
Applications
- Common mode noise filtering in electronic circuits
- EMI suppression in signal and power lines
- PCB-mounted interference reduction applications
Procurement Notes
Verify the specific suffix and packaging configuration against official manufacturer documentation before ordering. Confirm that the required inductance value and current rating align precisely with the target circuit design requirements. Ensure compatibility with standard SMT assembly processes and reflow soldering profiles specified for this component series.
Selection Notes
Select this component when a 330 µH common mode choke is required for space-constrained designs. Evaluate the 750 mA current limit to ensure it meets the operational load without saturation. Consider the unshielded nature of the device regarding potential magnetic coupling with adjacent components on the printed circuit board.
Part Context
This part belongs to the CM6149 series of common mode chokes manufactured by Delevan. The series offers various inductance values tailored for different filtering needs while maintaining consistent physical dimensions. These components are categorized under passive electronic components specifically designed for electromagnetic interference control in modern electronics.
Replacement Considerations
Cross-reference with other CM6149 series variants such as CM6149-104 or CM6149-683 if different inductance values are needed. Verify mechanical footprint compatibility when substituting with similar low-profile common mode chokes from other manufacturers.
