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.

Characteristics

  • Magnetic iron alloy allows high rated currents up to 9.9 A
  • Compact design
  • Magnetically shielded
  • High current capability and handles high transient current spikes
  • Low acoustic noise and low leakage flux noise
  • AEC-Q 200 qualified
  • Operating temperature: –40 °C to 125 °C
  • WE-MAPI 4020HT: High Temperature Series with operating temperature from -55 °C to +150 °C

Applications

  • DC/DC-converter for high current power supplies
  • DC/DC-converter for Field Programmable Gate Array (FPGA)
  • POL-converters
  • Portable power like PDA, digital camera
  • Mainboards/graphic cards
  • Battery powered devices
  • Wireless communication devices
  • Power supplies for smartphones, tablet PCs and other mobile devices
