Common Mode Chokes Procurement Notes

Verify compliance requirements carefully as this component is explicitly non-RoHS compliant and contains lead. Confirm that the manufacturing source is API Delevan or authorized distributor. Ensure the ordering suffix matches the reel packaging format if applicable. Validate the specific inductance value against schematic requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required for low-frequency common mode noise attenuation. The 270 mA current rating limits suitability for high-power applications. Verify thermal management capabilities given the 1.98 Ohm DC resistance. Consider the physical footprint constraints relative to the 21.3 mm x 18.8 mm dimensions during PCB layout.
