    Overvoltages and the associated high surge currents can damage, or even destroy electrical and electronic devices. Reliable overvoltage protection is therefore essential. On the basis of a new ceramic material, TDK has now developed a high-surge series of multilayer varistors that combine compact dimensions wi

    Initially regarded as toys, multicopters are now serious business. From simple surveying to future delivery solutions, entire businesses are emerging around the design, supply and use of multicopters. With increased adoption comes increased regulation and the multicopter itself needs to be capable of being piloted in

    The term “hot swap” refers to the practice of inserting or removing modules from a powered system. Hot-swap controllers are sometimes categorized together with power distribution switches; however, there are key differences that must be understood for proper system design. A hot-swap controller uses an external se

    Being a Sci-Fi geek, I am a fan of the late 1950’s Hollywood “cheesy” low budget Ed Wood movies typical of this genre. One of my favorite films is “Plan 9 from Outer Space,” in which aliens come to Earth to stop humanity from building a doomsday weapon that could destroy the entire universe. However, th
