Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched...

Bel Fuse announced the industry’s only surface mount, PPTC resettable fuse, line-volt-rated to 240 VAC...

Single-output switching regulator circuits can often be adapted to multiple output configurations with a minimum of changes, but these transformations usually call for custom wound inductors...

Fig 1’s circuit, which was developed to monitor the traffic of bumblebees into and out of the hive, differentiates “a-to-b” motion from “b-to-a” motion...

This issue had been previously addressed during pre-internet times in EDN of January 18,1990 but a further detailed look at the idea is warranted thirty-four years later...

Here is the circuit from a previous DI. Simple local low-noise voltage converter that can be used when a simple negative supply of low voltage is required. It is simple, and its efficiency can be improved by a very quick change...

Large currents flowing in a length cable can be measured using the voltage drop along the cable. It eliminates the need for a bulky shunt or expensive magnetic measurement method...

Many power-supply designs rely on accurately sensing the voltage across a current-sense element...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued that since the exponential voltage of a capacitor is qualitatively similar to inductor current...

In battery-powered applications in which power management is key, a microprocessor may adjust its core voltage corresponding to an increase or a decrease in clock speed, allowing full processing power when necessary but not wasting excess power when idle...
