Chassis Mount Resistors: HS250 2K2 F

Application Field

Chassis mount resistors are components used to regulate and control the flow of electrical current. The HS250 2K2 F is a product in this class which is specifically designed for use in military and aerospace applications.The resistor offers a low temperature coefficient, low noise, and high accuracy and stability. It is capable of operating in temperatures of up to 70°C without compromising its performance. The resistor is guaranteed to stay within its operating parameters even when subjected to rapid changes in temperature or when undergoing mechanical shock.The HS250 2K2 F is designed to be used in the very high RF frequencies, making it ideal for use in radio, microwave and radar applications. It can also be used for switching and regulation of DC power systems, or for providing resistance current paths in high-voltage systems.The HS250 2K2 F is available in a variety of endurance levels to suit different application needs, and provides a wide range of resistance values from 0.02Ω to 2.2KΩ. The resistor can be mounted to a variety of chassis configurations, including traditional circuit boards, ground planes, or aluminum housings.

Working Principle

The HS250 2K2 F works by providing a specific electrical resistance to the circuit. This resistance reduces the current flow through the system, the resulting voltage drop, and the power dissipation.When current is applied to the resistor, a small amount of energy is converted into heat, which is then dissipated by the chassis to the surrounding environment. The exact amount of resistance provided by the resistor is determined by its design and construction.The HS250 2K2 F is made up of two metal conductors, usually a tin or lead alloy, which are sandwiched between two insulating layers, usually ceramic. The two conductors are further separated by a thin film of resistive material, such as carbon or aluminum oxide.When an electrical current is applied to the resistor, the resistive material forms an electrical resistance to the current, thus reducing the overall current flow. The current passing through the resistor is also reduced due to the resistance created by the insulating layers which are further out from the center of the resistor.The HS250 2K2 F offers an advantageous combination of performance characteristics that makes it ideal for use in a wide range of applications. Its low noise levels, high accuracy and stability, and low temperature coefficient ensure that it can perform reliably and accurately in challenging conditions. The device also offers a wide range of resistance values, making it suitable for a variety of tasks.
