Sumida’s SPM series make use of our proprietary Power Supply in Inductor (PSI²) technology, with all components mounted inside the inductor. These modules also offer very high power density up to 1100 W/cu in. The magnetic material also has much better thermal conductivity than plastic, which avoids hot spots in the module. Consequently, these modules can offer very high power density up to 1100 W/cu in.
