Frequently Asked Questions

Which EMI-controlled signal interfaces designs benefit most from 744290121?

744290121 fits EMI-controlled signal interfaces when designers need 120 µH nominal inductance in a data line filter. The 0.0105 ohm DC resistance detail helps compare losses, filtering behavior, and board-level design margins.

How should layout engineers handle 9.5 mm height on 744290121?

For layout planning, verify 9.5 mm height against pads, keepouts, and assembly clearances. The 5.5 A rated current specification should be checked before committing the SMT or through-hole footprint.

When should procurement teams choose 744290121 for production builds?

Procurement teams should consider 744290121 when the BOM calls for a Würth Elektronik data line filter with 80 V rated voltage. Confirm lifecycle, date-code, and worldwide shipping requirements before buying.
