Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as Sumida products may be distributed under Sumida Corporation or Sumida America Components Inc. Confirm the pin configuration matches the vertical four-pin layout. Ensure the 2.2 mH inductance and 1.3 A current ratings meet the circuit requirements. Check for any updated datasheets regarding moisture sensitivity or RoHS compliance status before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when vertical through-hole mounting is required for power line applications. The 2.2 mH inductance value is suitable for standard EMI filtering tasks. Verify that the 240 milliohm DCR aligns with the system's voltage drop constraints. Ensure the 1.3 A current handling capacity exceeds the maximum operating current of the target application to prevent saturation or overheating.
