Common Mode Chokes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Pulse Electronics or authorized distributors before finalizing procurement. Confirm that the 60 mOhm DC resistance and 3.3 A current ratings align with your circuit requirements. Ensure the surface-mount footprint dimensions match your PCB layout constraints. Check for any recent product change notifications that may affect physical or electrical characteristics.

Common Mode Chokes Selection Notes

Select this component when dual-line common mode noise attenuation is required at high inductance values. The 3.3 A current rating suits moderate power applications. Consider the unshielded nature if magnetic coupling with nearby components is a concern. Verify thermal performance under continuous load conditions given the 125 C maximum operating temperature limit.
