The FSAM50SM60A and FSAM755M60A devices offer 50A and 75A ratings, respectively, and are made for the 5kW to 7.5 kW commercial and industrial inverter motor designs. They take up half the space of other solutions, with 60 × 31mm dual inline packages. They transfer heat through direct bonded copper substrates. They come with six IGBTs, six freewheeling diodes, three HVICs, one LVIC and one thermistor. They have integrated sensorless control and temperature monitoring, plus an integrated thermistor for over-temperature condition monitoring. They offer switching frequencies up to 20 kHz. They are lead-free, meet or exceed the joint IPC/JEDEC standard J-STD-020C and are compliant with current European Union requirements.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
