WE-MAPI SMD Shielded Power Inductor
The Würth Elektronik' WE-MAPI is the world's smallest metal alloy power inductor. Its efficiency is unprecedented.
It’s efficiency is outstanding and now available in new sizes and extended temperature versions with AEC-Q200 Grade 0 qualification for -55° to +150 °C operation temperature in the 4020HT series.
The power inductor was developed for the latest and upcoming switching regulator generations. It impresses with its innovative metal-alloy core material. The frameless design with direct wire connection significantly increases the effective magnetic volume and thus also the power density.
