LEMs transducer families are called; LXS, LXSR, LES, LESR, LKSR, LPSR. Each transducer can be mounted on printed circuit boards for non-intrusive and isolated measurements of DC, AC and pulsed nominal currents from 1.5A to 50A thanks to a multi-range configuration. These closed-loop current transducers are based on a LEM custom proprietary patented Hall Effect ASIC, allowing them to perform at the level of fluxgate transducers.
Mitsubishi Electric and the University of Tokyo Reveal New Mechanism for Enhancing Dependability of SiC Power Semiconductor Devices
The Darlington Transistor named after its inventor, Sidney Darlington is a special arrangement of two standard NPN or PNP bipolar junction transistors (BJT) joined together. The Emitter of one transistor is connected to the Base of the other to generate a more sensitive transistor with a much larger current gain being useful in applications where current amplification or switching is required.
