When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit. In a simple capacitor equivalent circuit ...

Charge pump circuits represent a pivotal technology in modern power management systems, utilising capacitors switched at high frequencies to convert a low input voltage into a higher, regulated output ...

FIGURE 1: This electrical schematic diagram shows the cooler’s single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor, and starting relay circuit section. July 6, ...

Don’t think simple passive components will be trouble-free in your designs. A component as simple as a capacitor can cause you big headaches. I was reminded of this when EDN editor Martin Rowe came ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

Over the last 40 years, a series of misconceptions regarding mica capacitor applications has led novice users to consistently over-derate wound or rolled mica/epoxy dielectric capacitors. The mined ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Most component testers require removal of a component to test it. [Mr Carlson] recently restored an old Paco C-25 in-circuit capacitor tester. He does a very complete video tearing it down and showing ...
