Frequently Asked Questions
Which DC-DC converter layouts designs benefit most from 744775122?
744775122 fits DC-DC converter layouts when designers need 22 µH nominal inductance in a chip power inductor. The 0.11 ohm DC resistance detail helps compare losses, filtering behavior, and board-level design margins.
How should layout engineers handle 3128 case size on 744775122?
For layout planning, verify 3128 case size against pads, keepouts, and assembly clearances. The 3128 case size specification should be checked before committing the SMT or through-hole footprint. It also provides 0.11 ohm.
When should procurement teams choose 744775122 for production builds?
Procurement teams should consider 744775122 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.
