Common Mode Chokes Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm packaging type, listed as bulk or reel depending on supplier, and ensure minimum order quantities align with distributor requirements. Validate that the specific batch matches the 270 µH specification and 2.2 A current rating before integration into final assemblies.

Common Mode Chokes Selection Notes

Select this component when a 270 µH inductance is required for common mode noise attenuation. Ensure the circuit operates within the 2.2 A DC current limit to prevent saturation. Verify that the 51 mOhm DC resistance meets power loss constraints. Check that the physical footprint fits the PCB layout and that the operating temperature range covers the application environment.

Common Mode Chokes Part Context

Part of the Delevan CM9900 series of common mode chokes. This series offers various inductance values for different filtering needs. The CM9900-274 specifically targets applications requiring moderate inductance with high current handling capabilities. It is manufactured by Delevan, a provider of passive components.

Common Mode Chokes Replacement Considerations

Check for exact 270 µH ±25% specifications. Ensure replacement parts support at least 2.2 A DC current and have similar physical dimensions (18.8 x 21.3 x 17 mm) and 5.1 mm lead spacing. Verify compatibility with existing PCB footprints and thermal management requirements.
