Common Mode Chokes Procurement Notes

Verify the specific suffix MT TAG against the official onsemi datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status through the manufacturer's latest documentation. Check for End-of-Life notifications or Product Change Notifications that may affect long-term availability or manufacturing sources before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when simultaneous EMI attenuation and ESD protection are required for 5V logic level interfaces. The 1.3pF capacitance value is critical for maintaining signal integrity at high frequencies. Ensure the WDFN-10 footprint matches the PCB layout requirements and that the 16A pulse current rating exceeds the expected transient energy levels of the target application environment.

Common Mode Chokes Part Context

This device belongs to onsemi's EMI41xx series of integrated filters. These components are engineered to replace discrete inductor and TVS diode networks. The series targets modern multimedia and mobile applications where board space is limited and signal speeds require minimal parasitic capacitance.

Common Mode Chokes Replacement Considerations

Consult the official onsemi substitution guide for verified alternatives. Generic equivalents may not match the specific 1.3pF capacitance or 16A peak current ratings. Verify package compatibility and thermal performance before considering cross-brand replacements.
