High Current with Low DC Resistance Inductors

TDK’s Power Cube Metal (PCM) series of inductors are a perfect selection for a high saturation current up to 80 A and a low R_DC.

The demanding requirements in the automotive area as well as for server and telecommunication applications increase in terms of higher current and performance improvement. The PCM120T series meets these demands and is ideally suited for interference suppression, like electric motors in xEV. Other applications include: PMIC, on-board charger, electronic power steering and for ADAS.

Features
