Low-compression-force gap-filler pads boost thermal efficiency of heat sinks
The compression characteristics of thermal gap fillers should be key considerations during a product’s early design phase. For applications that have delicate components or widely varying gap distances, Fujipoly created a line of Low Compression Force gap filler pads. These TIMs help avoid overstressing the printed circuit board (PCB) and fragile solder joints as the […]
New 200-V Schottky Barrier Diodes feature ultra-low reverse current
Rohm announced the availability of 200V ultra-low IR Schottky Barrier Diodes (SBD) optimized for automotive applications including powertrains and xEVs. The RBxx8BM/NS200 expands on the RBxx8 lineup of SBDs enabling high-temperature operation that have already been proven in the automotive market in Japan.
