Common Mode Chokes Procurement Notes

Verify the specific part number against official Panasonic documentation to confirm impedance and current ratings. Ensure compatibility with standard SMD reflow processes. Check for RoHS compliance status in the latest datasheet before finalizing procurement specifications.

Common Mode Chokes Selection Notes

Select this component when space-constrained designs require multi-line noise filtering. The 0804 footprint suits compact layouts. Evaluate the 160 mA current rating against circuit requirements. Confirm that the 90 Ohm impedance aligns with target frequency attenuation needs.

Common Mode Chokes Part Context

This device belongs to the EXC series of common mode chokes. It serves as a passive EMI suppression solution. The array configuration allows simultaneous filtering of multiple differential or single-ended signals. It replaces discrete inductors to save board area.

Common Mode Chokes Replacement Considerations

Consult Panasonic's official cross-reference lists for verified substitutes. Generic equivalents may not match the 90 Ohm impedance or 160 mA current limits. Verify package dimensions and pinout compatibility before substitution.
