www.quadtech.comOver the past 3-1/2 years, microprocessor current has increased by a factor of 5 and equivalent series resistance (ESR) has dropped by a factor of 7. Next-generation microprocessors ...

The Quick-Check Transformer & Capacitor Tester from HD Electric is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the ...

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 ...

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 ...

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

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, ...

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 ...

A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

There is a general trend of making electronics smaller and with more functionality. This translates into: “Cram it in there,” so naturally designers look to find smaller and smaller parts. What was on ...
