Power Resistor Market: Introduction
In an electric circuit, power resistors endure and distribute a huge amount of power. This power dissipation by a power resistor results in accelerated increase in temperature, after which the power resistor starts dissipating power through the circuit board and the surrounding atmosphere. In order to minimize this kind of dissipation and the consequential hazardous failure conditions, raw materials having high thermal conductivity are used to develop power resistors. These constituents of power resistors enable efficient cooling. Power resistors are often coupled with heat sinks to facilitate the efficient dissipation of high power. Under maximum load, some power resistors require air- or water-based forced cooling.

Today, the companies in operating in the power resistor market are focusing on developing power resistors that dissipate huge amount of power, while keeping their size as small as possible. With regards to the resistor technology, the companies offer power resistors as wired resistors and power resistors having metal foil in their TO housing.
Power Resistor Market: Drivers & Challenges
Power resistors made of high thermal conductivity materials, especially carbon composite resistors, have the ability to endure high energy pulses. This mitigates the risk of circuit damage or failure. Also, most of the raw materials required to develop power resistors are not much expensive. If the standard usage specifications are met, power resistors are very reliable, efficient and long lasting. These factors are expected to drive the growth of the global power resistor market over the forecast period.
However, due to humane error, operating power resistors above their specified power rating results in highly exothermal conditions. This causes severe consequences, such as the resistor can ignite and destroy the circuitry. Some other consequences of operating power resistors above the rated power include, short circuits, reduction in circuit and power resistor life span, and a shift in the overall resistance value. These factors challenge the growth of the global power resistor market.
