Common Mode Chokes Procurement Notes

Verify the suffix '-B' indicates bulk packaging when ordering. Confirm that the inductance tolerance is +30%/-50% at 1 kHz and the maximum DC current is 1.4 A. Ensure the vertical mounting style and radial leads match the target PCB layout. Check RoHS compliance status via official documentation before finalizing procurement specifications.

Common Mode Chokes Selection Notes

Select this component for applications requiring 27 mH common mode inductance with a 1.4 A current rating. The vertical form factor suits boards where height is constrained but footprint allows radial placement. Verify that the operating temperature range of -40°C to +105°C meets environmental requirements. Compare DC resistance and physical dimensions against alternative chokes if space or efficiency is critical.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. It is specifically engineered for power line EMI suppression. The CMF23V-273141-B variant offers a fixed inductance value optimized for general-purpose AC filtering tasks. It shares the series' robust construction and thermal performance characteristics.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 27 mH inductance, 1.4 A current rating, and vertical radial package. Verify equivalent DC resistance and temperature range. Cross-reference with other Triad Magnetics CMF23V variants if parameter adjustments are acceptable.
