Platinum wire-wound detectors comprise a pure platinum wire wound into a miniature spiral and located within axial holes in a high purity alumina rod. The freedom of movement of the platinum wire ...

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, ...

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 ...

If you do, Vishay has turned that into reality with a series of pick-and-place-friendly cemented wire-wounds. They are actually the company’s existing 3W AC03-CS series of fuseable resistors, with the ...

(click thumbnail)Fig. 1: Fling one of these to your promotions director. (click thumbnail)One of the best things you can do to foster teamwork among fellow department heads is to pass on useful ...

Editor’s note: The following is a ‘white’ paper that Mike Chesselet and Edwin G. Pettis wrote on January 15, 2000 about the history of resistors. Since it was written, there have been some advances in ...

Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

What do you do, when you want an ohm? What is an ohm, for that matter? Take a wander over to the textbook definitions, and you’re soon deep in a world of coulombs and parallel infinite planes one ...
