My recent DI contribution (Another silly simple precision 0/20 mA to 4/20 mA converter, Ref. 1 ) used the LM337 regulator in a novel circuit arrangement to translate an input 0-20 mA current source into a 4-20 mA two-wire transmitter current loop ...

We’re all familiar with thermally activated fuses, where the conducting element self-heats due to current flow, melts at a defined current value, and breaks the flow path. They are simple in concept (although they have their own subtleties, ...

I have always been intrigued by the many ways scientists and engineers have devised to sense basic physical parameters such as temperature, pressure, voltage, current, and electric fields, to cite just a few. In some cases, the challenge is the ...

Any semiconductor has limits on how much voltage, how much current, and for how much time combinations of voltage and current can be supported in normal usage. Sometimes that information is provided as part of the device’s datasheet, and ...
