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 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 ...

Additions to the RWT series vertical-mount, thermally-fused wire-wound resistors include 2W and 7W elements to accommodate a broader range of commercial, consumer, and industrial applications.

Resistor: A passive chunk of material that resists the flow of electrical current. A terminal is connected to each end you’re done. What could be simpler? It turns out it’s not so simple at all.
