Having acquired some piece of old electronic equipment, be it a computer, radio, or some test gear, the temptation is there to plug it in as soon as you’ve lugged it into the ‘shop. Don’t be so hasty.

As the economy continues to change, chances are good that you’re examining every aspect of your business for ways to improve your bottom line. A significant opportunity may be found by taking a close ...

Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, ...

It is easy to dismiss passive components like resistors and capacitors as a boring subject. [James Lewis] of KEMET Capacitors would disagree. He gave a talk about capacitor tech that is both ...

Individual pieces of graphene have some pretty amazing properties, but finding a way to produce bulk materials that make good use of those properties has been rather challenging. Now, researchers have ...

Ever wonder what goes on inside of an electrolytic capacitor? Nick Visic from AiSHi Capacitors shows how these popular capacitors work in this tear-down video from DesignCon. The screw terminal ...

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

Designing a high-voltage capacitor charger or power supply up to a thousand volts is not a trivial task. A discrete solution using a general-purpose flyback PWM controller with an optocoupler, ...

The circuit in Figure 1a comprises a voltage follower, IC 1, and the reference-voltage source of IC 2. IC 1 is an Analog Devices AD8661 op amp, which has a guaranteed input-bias current of no more ...
