WE-MAPI Size 4020 High Current Power Inductors

Würth Elektronik WE-MAPI Size 4020 Power Inductors come in a 4.1mm x 4.1mm x 2.1mm package and are shielded, surface mount devices with high current capabilities. This series was designed to also achieve low DCRs and high saturation currents for optimum performance in high switching frequency DC/DC converters (>1MHz).  Other features of these WE-MAPI inductors include low acoustic noise, low leakage flux noise, and a -40ºC to +125ºC operating temperature range suitable for industrial applications.
