In all kinds of engineering, we build on abstractions in a kind of inverted pyramid. Lots of people can, for example, design a system using ready-made building blocks on printed circuit boards. Fewer ...

The VRH320 Variable Wire Wound Resistor available from ARCOL Resistors has a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment, instruments, ...

The inventor Otis Frank Boykin, known for inventing the wire precision resistor, was born on August 29, 1920 in Dallas, Texas. Boykin’s mother, Sarah Boykin, worked as a maid before dying in 1921 ...

The SWT (silicone coated) and EWT (vitreous enamel coated) series of high-power tubular wire-wound resistors have been expanded to include the industry’s most common wattages and hardware. Both series ...

It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.

The resistor is one of the simpler electronic components. Engineers seldom examine resistor characteristics until there's a resistor-related problem with a circuit design. You can probably resolve 90% ...
