Chassis Mount Resistors: HSC20047RJ Application Field and Working Principle

A chassis mount resistor is an electronic component that has a resistance value and is mounted on a printed circuit board assembly or chassis, depending on the design. It is used to provide an electrical resistance in an electrical circuit, so that the current flow in the circuit is limited and thus, the voltage is regulated. In addition, it acts as a safety measure to protect sensitive components from high currents and voltage surges, and to optimise power distribution. The chassis mount resistor is commonly used in telecommunications, audio/visual, automotive, consumer electronics and industrial equipment.The HSC20047RJ chassis mount resistor is a special type of resistor, designed with high stability and high reliability. It has a temperature coefficient of resistance of 0.005 Ω/°C, making it suitable for applications that require thermal stability in extreme conditions. Furthermore, its resistance range from 0.5 Ohms to 1 MOhms allows the user to select the desired value for the specific application. Its power rating is 2W and it is designed to be mounted on a PCB or a material for external mounting. It is insulated with a UL94V-0 grade flame retardant material, ensuring safety in use.The working principle of the HSC20047RJ chassis mount resistor is based on the Joule’s law: when an electrical current passes through a metal conductor, it generates heat due to resistance. This heat is inversely proportional to the resistance of the conductor. Thus, by selecting the appropriate resistance value for an application, the current in the circuit can be limited and the heat generated is kept to a minimum. In this way, the power dissipated by the resistor is also kept to a minimum. The current limiting ability of the HSC20047RJ is further enhanced by its tolerances. The tolerance of this type of resistor is 0.5%, ensuring high accuracy and low variation. Its temperature coefficient of resistance and its high stability make it suitable for use in applications that require precision and reliability, such as automotive equipment, industrial equipment, telecommunications and medical equipment. It is also suitable for applications that require high voltage protection, such as consumer electronics and audio/visual systems.The HSC20047RJ is a robust and reliable resistor, designed to perform reliably in extreme conditions. Its tolerances, temperature coefficient of resistance, and stability make it suitable for a wide range of applications, where reliability and precision are essential. It is a versatile and dependable component, capable of withstanding high temperatures and voltage surges.
