In addition, it can be used for controlling motors, heating elements and lights.

Working Principle

The chassis mount resistor works using the principle of resistance. It is constructed from aluminum with a resistive coating of a durable material. The aluminum acts as a conductor and the coating acts as a resistor. When a voltage is applied to the resistor, the electric current is opposed by the resistive coating. This causes the electric current to reduce in strength and increases its path. This resistance is measured in ohms, which is a measure of the electrical resistance in an object. The greater the ohms, the greater the resistance.

The RER40F5490RC02 has a resistance range of 10 - 22K ohms. The high operating temperature allows for greater power to be handled and therefore is used in a variety of higher power applications, including laser modules, industrial automation, and more. This chassis mount resistor has superior surge and over-current protection, making it ideal for applications that are subject to wide voltage fluctuations. It also has a low thermal resistance, which reduces overall temperature rise.

In summary, RER40F5490RC02 is a reliable and effective chassis mount resistor that is frequently used in a wide variety of industrial and consumer applications. It has a wide range operating temperature, superior surge and over-current protection, and a low thermal resistance, making it suitable for higher power applications. Consequently, this chassis mount resistor is the perfect choice for reliable performance.
