If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

HD Electric Co.'s Cap Check line of capacitor testers are designed to identify internal problems with a capacitor or capacitor bank and have proven to be a valuable asset in maintaining both ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Normally, a typical multimeter is designed to measure parameters such as voltage, current and resistance over a wide range of values. This analog capacitance meter has 5 switched range values of 1nF, ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester ...

The transformer and capacitor tester, developed by Hastings, a global supplier of hot line tools and equipment, ensures the safety of hotline workers so that they can perform their jobs with ...
