Common Mode Chokes Procurement Notes

Verify the specific suffix requirements against the official Gowanda datasheet, as variations may exist between leaded and lead-free versions. Confirm that the 12 mΩ DCR and 7.7 A current ratings align with your system's thermal and electrical constraints. Ensure the horizontal footprint matches your PCB layout guidelines before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a robust common mode choke is required for high-current applications. The low DCR minimizes power loss, while the wide operating temperature range ensures reliability in harsh environments. Compare the 100 µH inductance value against circuit requirements to ensure adequate noise attenuation without affecting desired signal frequencies.
