CMF23H-683900

Common Mode Chokes Overview

The Triad Magnetics CMF23H-683900 is a vertical mount common mode inductor designed for through-hole PCB integration. It features a single-channel configuration with an inductance of 68 mH, measured at a test frequency of 1 kHz, and exhibits a tolerance range of +30% to -50%. The component supports a maximum DC current of 900 mA and possesses a maximum DC resistance of 1.21 Ohms. Physical dimensions are specified as 29 mm in length, 15.5 mm in width, and 27 mm in height, with a lead diameter of 0.7 mm. It operates within a temperature range of -40°C to +105°C.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for single-line circuits via radial through-hole termination.
• Engineered for high thermal stability with an operational range extending up to +105°C.
• Constructed as a frame choke type inductor suitable for vertical mounting on printed circuit boards.

Common Mode Chokes Applications

• Power supply input filtering
• EMI suppression in electronic equipment
• Signal line noise reduction

Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CMF23H-683900-B denote bulk packaging configurations. Confirm that the required inductance tolerance of +30%/-50% aligns with the design specifications. Ensure the 900 mA current rating meets the application's peak load requirements without saturation. Cross-reference the physical footprint dimensions against the target PCB layout to guarantee proper clearance and mounting compatibility.

Common Mode Chokes Selection Notes

Select this component when a 68 mH common mode choke is required for vertical PCB assembly. The choice is appropriate for applications demanding a maximum DC current of 900 mA and a low DC resistance of 1.21 Ohms. Consider the wide operating temperature range if the environment exceeds standard conditions. Verify that the radial lead style matches the manufacturing process capabilities.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. The series includes various inductance values and current ratings, such as the CMF23HK kit which contains multiple values including the 68 mH variant. The CMF23V and CMF23H sub-series share similar form factors but may differ in specific electrical characteristics or packaging options.

Common Mode Chokes Replacement Considerations

The CMF23V-683900-B is a verified substitute offering identical electrical parameters including 68 mH inductance and 900 mA current rating. Both components share the same vertical mounting style and radial termination type. Verify mechanical fit before substitution.
