Common Mode Chokes Procurement Notes

Verify the specific suffix 'A' against the official Littelfuse datasheet to confirm impedance tolerance and material composition. Confirm RoHS3 compliance status as required by your manufacturing specifications. Ensure the ordering part number matches the exact electrical parameters needed for your circuit design before procurement.

Common Mode Chokes Selection Notes

Select this component when designing for space-constrained applications requiring robust ESD protection alongside high-frequency noise filtering. The 1210 footprint allows for efficient PCB layout while maintaining the necessary electrical performance for digital signal integrity. Consider the 100 mA current rating to ensure it aligns with the operational requirements of the target interface.

Common Mode Chokes Part Context

This component belongs to the LCFA series of common mode noise filters manufactured by Littelfuse. The series is engineered to suppress unwanted electromagnetic interference in modern electronic devices. The LCFA series utilizes advanced materials to achieve high impedance values in a miniature surface-mount package suitable for automated assembly processes.

Common Mode Chokes Replacement Considerations

Consult the Littelfuse discontinuation notice for potential end-of-life status. Verify cross-reference compatibility with other 1210 package common mode chokes having similar 90-ohm impedance and 100 mA ratings if substitution is necessary.
