Power Passives and Discretes

September 2015
Many applications in industrial, instrumentation, optical communication and healthcare industry use multi-channel data acquisition systems that result in increased printed circuit board (PCB) density and thermal power dissipation challenges.  The need for increased channel density in these applications

The “Energiewende” (energy transition) has resulted in a shift in thinking not only about the generation of electrical energy, but its distribution and consumption as well. Efficient approaches are needed for energy production and transfer on the one hand, and consumption on the other. What plays a role

Today’s industrial applications demand power supplies capable of delivering ever-higher levels of power density. That trend is escalating as regulatory agencies around the world impose new regulations to achieve higher efficiency, not only at full load, but also in standby mode and across the entire load spectrum.

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

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
