Common Mode Chokes Procurement Notes

Verify the specific suffix designation, as variations such as the base model may differ in electrical characteristics or packaging. Confirm that the 17.8 mH inductance and 2.7 A current rating align with your circuit requirements. Ensure the through-hole radial package dimensions fit your PCB layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode rejection at high frequencies. The 17.8 mH value offers significant impedance to noise while maintaining a low DC resistance of 196 mΩ to minimize power loss. The 2.7 A current rating suits moderate-power applications, and the wide operating temperature range ensures reliability in varied environments.
