Ultimate Guide to Resistors

Ultimate Guide to Resistors

Introduction Resistors are probably the most common and well known of all electrical components. This guide to precision and power resistors answers all your questions about the four main resistor technologies and their performance. In these pages, you’ll find a...

Resister Characteristics And Their Definitions

Here’s a brief glossary of the most important terms used when describing resistors’ characteristics. Tolerance Resistor tolerance is the deviation from the nominal value. It is expressed as a ±%, measured at 25°C with no load applied. Some resistor designs have...

Wirewound Resistors

Like every component, the fabrication technology used in resistor manufacture has changed over time and resistive films, for example, have made a significant contribution in allowing the cost-effective mass production of devices that are increasingly miniaturized. Yet...

Thick Film and Thin Film Chip Resistors

Film technology products have developed sufficiently to replacing older carbon resistors. There are two common film types, thick film and metal or thin film, with thick film being the most prolific type of resistor used in electronic devices. These devices may look...

Metal Foil Resistors

Metal foil resistors offer unmatched performance for the highest precision applications, without compromising on accuracy, stability or speed. They are constructed by adhering a metal alloy foil, usually nickel/chromium (Nichrome) with some additives,to a ceramic...

Power and Heat Sink Dimensioning

In any system where heat dissipation could affect the components’ performance, understanding power dissipation for the purposes of selecting the right heat sink is very important. Let’s take a closer look at the power dissipation of resistors. Standard Conditions for...
