Common Mode Chokes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct electrical characteristics and packaging configuration. Confirm that the required safety certifications match the target market regulations. Check lead times as availability may vary. Ensure the through-hole footprint dimensions align with the PCB design constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 27.7 mH inductance at 10 kHz is required for two-line power filtering. Ensure the application current does not exceed 630 mA to maintain performance. Verify that the 820 milliohm DCR meets the voltage drop requirements. Confirm that the vertical through-hole form factor fits the assembly process and enclosure space limitations.
