CMT908-H2

Common Mode Chokes Overview

The Triad Magnetics CMT908-H2 is an encapsulated toroidal common mode filter inductor designed for power line EMI suppression. It features a radial termination style and belongs to the CMT series. Key electrical specifications include a maximum DC resistance of 40 mOhms, a maximum DC current rating of 5.2 A, and an inductance of 4 mH measured at 10 kHz. The component has a tolerance of 10% and supports two lines. Physical dimensions are approximately 36.83 mm in length and 20.32 mm in width.

Common Mode Chokes Feature Summary

• Provides common mode EMI noise suppression for power lines
• Utilizes encapsulated toroidal core construction for dependability
• Designed for use in various types of power supplies

Common Mode Chokes Applications

• Power supply noise elimination
• Common mode EMI suppression circuits
• Power line filtering applications

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -H2) against official Triad Magnetics documentation to ensure correct electrical parameters such as inductance and current rating. Confirm RoHS compliance status through the manufacturer's product trade compliance files. Ensure the radial termination type matches the target PCB layout requirements before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing power supplies requiring robust common mode noise reduction. The 5.2 A current rating and low DC resistance make it suitable for higher power applications. Verify that the 4 mH inductance value meets the specific frequency attenuation requirements of the design. Ensure physical space accommodates the toroidal dimensions.

Common Mode Chokes Part Context

This part is part of the Triad Magnetics CMT series of common mode inductor kits. These kits often include multiple variants (such as V1-V4 and H1-H4) to provide different inductance and current combinations. The CMT908-H2 specifically represents one configuration within this broader family of encapsulated toroidal inductors intended for industrial and commercial power electronics.

Common Mode Chokes Replacement Considerations

Consult Triad Magnetics official documentation for direct substitute part numbers within the CMT908 series. Variants such as CMT908-H3 or CMT908-V4 may offer different electrical characteristics but share similar form factors. Cross-referencing datasheets is required to match inductance and current ratings precisely.
