When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

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 ...

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, ...

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, ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Marwell Corporation will feature its AMI Capacitor Monitor adapter in Booth #3708 at DistribuTECH 2015. Marwell will showcase products developed to address the growing need for improved efficiency, ...
