CMF23H-473111

Common Mode Chokes Overview

The CMF23H-473111 is a common mode inductor from the Triad Magnetics CMF series, designed for through-hole mounting. It features an inductance of 47 mH with a tolerance of +30%/-50% at 1 kHz and a maximum DC current rating of 1.1 A. The component has a maximum DC resistance of 884 mOhms and operates within a temperature range of -40°C to +105°C. Physical dimensions are 26.5 mm in length, 24.8 mm in width, and 14 mm in height, with 0.7 mm lead diameter.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for two-line circuits
• Supports horizontal through-hole installation
• Rated for high-temperature operation up to 105°C

Common Mode Chokes Applications

• Common mode filter chokes
• EMI suppression in power lines
• Signal integrity protection in electronic assemblies

Common Mode Chokes Procurement Notes

Verify the specific suffix requirements when ordering, as packaging variations such as bulk options may exist (e.g., CMF23H-473111-B). Confirm that the 1.1A current rating and 47mH inductance align with your circuit design constraints. Ensure compatibility with standard through-hole assembly processes given the radial lead configuration and specified physical footprint dimensions.

Common Mode Chokes Selection Notes

Select this component when a 47 mH common mode choke is required for applications handling up to 1.1 A continuous current. The wide inductance tolerance (+30%/-50%) should be considered during circuit simulation. Verify that the 884 mOhm DC resistance meets voltage drop limitations. The robust thermal rating supports environments requiring operation up to 105°C without derating concerns.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF23 series of common mode inductors. The series includes various kits like CMF23VK and CMF23HK containing multiple values. Individual parts like CMF23H-473111 are available separately. The series is characterized by through-hole construction and standardized dimensions suitable for general-purpose EMI filtering tasks.

Common Mode Chokes Replacement Considerations

Direct substitutes include CMF23H-473111-B, which shares identical electrical specifications but differs in bulk packaging. Other CMF23 series variants offer different inductance values but maintain similar form factors.
