Resistor Primer: CONDUCTORS AND INSULATORS

All materials are either conductors or insulators; a material will either conduct electrical current, or impede its flow. Not all conductors are equally capable of supporting current flow. Copper is a better conductor than nickel. Silver is a better conductor than...

Power Wirewound Resistors

When modern circuits need power resistors, the choice is often wirewound. Today’s wire-wound resistors are rugged and reliable. They are small and compatible with modern PC-board and surface mount manufacturing systems. And, new technology resistors still fall...

Wirewound Resistors

Wirewound resistors have been around for a long time. They enjoy a long life because they have some very important features not duplicated by new technology products. If you must optimize circuit designs where precision is important, you should understand those...
