Common Mode Chokes Procurement Notes

Verify the specific suffix KED against official Coilcraft documentation to confirm pinout and tolerance specifications. Ensure compatibility with automated pick-and-place equipment due to the SMD package. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration into production lines.

Common Mode Chokes Selection Notes

Select this component when high thermal stability and automotive reliability are required. The 12x12mm footprint offers a balance between current handling and board space. Consider the 10% tolerance for precision applications. Verify that the 3.2A current rating meets the circuit's peak load requirements without saturation.

Common Mode Chokes Part Context

This part belongs to the MSD1278H series, which includes various inductance values and tolerances. The 'H' denotes high-temperature performance, while 'KED' specifies the 10% tolerance and specific packaging. It is distinct from the standard MSD1278 series by its extended temperature range and automotive qualification.

Common Mode Chokes Replacement Considerations

MSD1278H-564MLD is a potential substitute with 20% tolerance. MSS1278H-564KED may be considered if single-ended inductance is acceptable instead of coupled functionality. Always verify electrical parameters and physical dimensions against the original design requirements.
