When you're editing 4K videos or running high-resolution AAA games on your laptop, it's easy to overlook the components working quietly in the background to keep everything running smoothly. Modern ...

Do you sometimes need an inexpensive precision power supply? This Design Idea presents a precision power supply that has thermal overload protection and short circuit protection, and can supply 100mA ...

If an engineer’s design demands a precision and stable capacitor, she or he will usually turn to NPO-type multi-layer ceramic (MLCC). This old standby is still the best. If you haven’t checked them ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

The author writes occasionally here about restoring vintage electronics. Vintage equipment relies on many components to run properly. Let’s focus today on what capacitors do in this process. A ...

Power outages lasting just a few seconds can impact a system’s operating functions and also cause a loss of important data. In the past, a UPS (uninterruptible power supply) might have been used as a ...
