Frequently Asked Questions
Which DC-DC converter layouts designs benefit most from 7440660022?
7440660022 fits DC-DC converter layouts when designers need 2.2 µH nominal inductance in a chip power inductor. The 0.0105 ohm DC resistance detail helps compare losses, filtering behavior, and board-level design margins.
How should layout engineers handle 3939 case size on 7440660022?
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 0.0105 ohm.
When should procurement teams choose 7440660022 for production builds?
Procurement teams should consider 7440660022 when the BOM calls for a Würth Elektronik chip power inductor with 3.8 mm height. Confirm lifecycle, date-code, and worldwide shipping requirements before buying.
