The resistor is the most common and well-known of the passive electrical components, and there are many resistor technologies currently being used in various commercial, industrial, automotive, and military markets. This white paper introduces new engineers to wirewound resistor technology and a few of their classifications.
Wirewounds have been on the market for a long time and are used extensively in commercial and industrial applications — whether it’s to drop voltage, restrict inrush current, or act as heaters and fuses. In electric vehicles (EV) and hybrid electric vehicles (HEV), they are also utilized as pre-charge and discharge resistors.
Read this white paper from Vishay to learn more about the basics of wirewound resistor technology.
