Frequently Asked Questions

Which DC-DC converter layouts designs benefit most from 744066221?

744066221 fits DC-DC converter layouts when designers need 220 µH nominal inductance in a chip power inductor. The 0.74 ohm DC resistance detail helps compare losses, filtering behavior, and board-level design margins.

How should layout engineers handle 3939 case size on 744066221?

For layout planning, verify 3939 case size against pads, keepouts, and assembly clearances. The 3939 case size specification should be checked before committing the SMT or through-hole footprint. It also provides 0.74 ohm.

When should procurement teams choose 744066221 for production builds?

Procurement teams should consider 744066221 when the BOM calls for a Würth Elektronik chip power inductor with 2 pins pin count. Confirm lifecycle, date-code, and worldwide shipping requirements before buying.
