LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

Environmental systems that precipitate dust and carbon particles frequently use high-voltage dc power supplies. However, failure of high-voltage components caused by a change in their properties over ...

Milpitas, Calif. — Linear Technology's new LTC4213 electronic circuit breaker senses load currents with the R DS(ON) of an external MOSFET, which eliminates the need for a sense resistor. The company ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

The recommended maximum total voltage drop on branch-circuit conductors is ____%. Article 210 outlines the requirements for branch circuits. Branch-circuit rating rules are covered in Part II of this ...

Pickering Interfaces, a supplier of modular signal switching and simulation solutions for use in electronic test and verification, has announced a new family of high voltage programmable resistor ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
