A power resistor is a resistor designed to dissipate large amounts of power and manufactured in a compact physical package. Resistors are capable of absorbing electrical power due to the presence of voltage across them. The power absorbed is converted into heat – greater the electrical energy, the greater the heat generated. Every resistor has a maximum power rating which is determined by its physical size. Generally, the greater its surface area the more power it can dissipate safely into the ambient air or into a heat-sink. Read More
Power resistors are produced using various materials. They are also designed in various construction and mounting types. The selection of the right resistor depends on the products they are used in and their Industry and Application. Power resistors may be accompanied by various additional standardized or custom accessories for easy and compact installation.
Low ohmic, low power value resistors are generally used for current sensing applications. High power resistors are used in heat-dissipating applications. Power resistors find wide applications in Automotives, Railway traction, Energy Conversion, Industrial Automation, Defence Equipment, and Healthcare.
