Common Mode Chokes Procurement Notes

Verify the specific revision status and datasheet version before procurement, as component specifications may be subject to change or obsolescence notices. Confirm that the surface-mount footprint matches the design layout requirements. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference the manufacturer's part number with authorized distributors to avoid counterfeit components.

Common Mode Chokes Selection Notes

Select this component when a low-profile surface-mount solution is required for common mode noise reduction. The 1.1 A current rating suits moderate power applications. Verify that the 460 µH inductance provides adequate attenuation at the target frequency of 100 kHz. Ensure the PCB land pattern accommodates the vertical 4-pin package dimensions.
