Common Mode Chokes Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as indicated by distributor part numbers. Confirm RoHS3 compliance status and ensure the supplier provides valid traceability documentation for the manufacturing batch. Check for any recent product change notices regarding package dimensions or material composition before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when high current capacity and low impedance are required for surface mount applications. The 45 µH inductance value is suitable for specific frequency attenuation requirements at 100 kHz. Ensure the PCB layout accommodates the 11.43 mm x 11.43 mm footprint and 6.00 mm maximum height constraints. Verify thermal management capabilities given the 160°C operating limit.
