Frequently Asked Questions
Which converter rails are a good match for MSS1278T-104MLD?
MSS1278T-104MLD is a power inductor for DC/DC converter and filtering rails where 100 uH inductance and up to 2.2 A current capability are appropriate.
How should designers account for winding resistance in efficiency checks?
The listed DC resistance is 0.1502 ohm, so designers should include I-squared-R loss when estimating heat rise and regulator efficiency under load.
What package style should purchasing compare against alternates?
This Coilcraft part is a rectangular molded power inductor with 2 terminals, so replacement approval should compare pad layout, height, and current rating.
Why is it relevant for automotive sourcing reviews?
The part is presented as AEC-Q200 oriented and rated for -40°C to 125°C operation, supporting automotive and industrial procurement checks for harsh environments.
