A good insurance plan is not just good to know about, in many aspects of daily life it is indispensable. In the case of Class X and Class Y capacitors, they are required to function reliably in all parts of mains-connected electrical devices, as they offer a form of insurance — we expect them to protect things th

When I started working with eGaN FETs almost six years ago, I had no idea what to expect from this technology. We had our first preliminary datasheet and even though I had no idea what to expect, it was obvious that, on paper, these devices were much better than your typical MOSFETs – already beyond the theoretical si

Motors are everywhere in our world, it seems. Consider our vehicles, for example. When is the last time you had to hand-crank a car window up and down to pay a highway toll? Or, for that matter, when did you last manually adjust the seat position or rear-view mirror angles? Typically, motors drive all of these as
