CMT-8104-B

Common Mode Chokes Overview

The Triad Magnetics CMT-8104-B is a power line common mode choke designed for through-hole mounting. It provides an inductance of 10 mH at 1 kHz with a maximum DC current rating of 2.4 A. The component features a maximum DC resistance of 170 mOhms and supports an AC voltage rating of 1500 V (1.5 kV). It operates within a temperature range of -55°C to 105°C and is constructed using UL rated 130°C Class B materials.

Common Mode Chokes Feature Summary

• Provides superior EMI suppression for power lines
• Constructed with UL rated 130°C Class B materials
• Features unshielded design for radial PCB mounting

Common Mode Chokes Applications

• Power supply input filtering
• Electromagnetic interference suppression in electronic equipment
• AC power line noise reduction

Common Mode Chokes Procurement Notes

Verify the specific suffix 'B' against the manufacturer datasheet to confirm exact mechanical dimensions and pin configuration, as suffixes may indicate variations in lead form or packaging. Ensure the selected component meets the required safety certifications such as UL, CSA, IEC, or VDE for the target application region. Confirm that the 170 mOhm DCR and 2.4A current rating align with the circuit's thermal and electrical constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 10 mH inductance at 1 kHz is required for common mode noise attenuation on power lines. The 2.4 A current rating suits moderate power applications, while the 1500 V AC rating ensures adequate isolation. Consider the unshielded nature if magnetic coupling with nearby components must be minimized, and verify that the through-hole package fits the available PCB real estate.

Common Mode Chokes Part Context

The CMT-8104-B belongs to the CMT series of common mode chokes from Triad Magnetics. This series is engineered for general-purpose EMI suppression in power line applications. The part utilizes a vertical, 4-pin through-hole package, distinguishing it from surface-mount alternatives. It is part of a broader family of filters designed to meet various international safety standards for electronic devices.

Common Mode Chokes Replacement Considerations

The CMT-8104 is a compatible variant within the same series. Verify that the base model meets all electrical specifications, including the 10 mH inductance and 2.4 A current rating, before substitution.
