Common Mode Chokes Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to ensure compatibility. Confirm that the required inductance value and current rating meet the circuit design specifications. Check for RoHS compliance status as indicated in the source data. Ensure the packaging format aligns with assembly requirements.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation. The 170 mA current rating limits suitability for high-power applications. Verify that the physical dimensions fit the available PCB space. Consider the unshielded nature of the component regarding proximity to sensitive traces.

Common Mode Chokes Part Context
