Chassis mount resistors are passive electronic components that possess resistive properties and provide resistance to the flow of electric current when connected to a circuit. A chassis mount resistor, such as the HSA25R22J, is a single-in-line (SIP) resistor that is designed to mount within a chassis and withstand the operating environment. This type of resistor is widely used in military, aerospace, and medical applications, where a combination of high power and long-term stability are required.

The HSA25R22J is a surface-mount resistor made from silvered molybdenum wire wound around a ferrite core. The device consists of a one-piece metal housing that houses the wire-wound elements and features a stud mounting system that allows for easy installation. The device has an operating temperature range of -55°C to +150°C and its electrical characteristics can be tailored to meet specific requirements. Its power rating is up to 25 watts, and its resistance range is from 2.2 ohms to 22 ohms.

The working principle of a chassis mount resistor is simple. When electric current passes through the resistor, it meets with resistance — often expressed as ohms. This resistance restricts the flow of current and causes electrical energy to be converted into heat, thus dissipating the current. The resistor also absorbs some of the energy and stores it until it is discharged, in which case it produces a voltage — meaning that it is also classified as a passive component.

The features of the HSA25R22J make it ideal for various applications, such as power supplies, PA systems, current-limited circuits, and laser and other high-voltage circuits. It is also designed to provide a high level of protection against surges, transients, and voltage spikes. In addition, the HSA25R22J has a wide frequency response range making it suitable for use in many AC and DC applications. The device also features extended overload protection capabilities, which can reduce the potential for catastrophic damage in the event of an overload.

In summary, the HSA25R22J is a highly durable chassis mount resistor that is suitable for use in a variety of applications and environments. It features a one-piece metal housing that houses the wire-wound elements and provides an extended overload protection capability. The device’s temperature range and electrical characteristics can be tailored to meet specific requirements, and its power rating is up to 25 watts. Its working principle is simple; when electric current passes through the resistor, it meets with resistance and absorbs some of the energy while dissipating the current. Overall, this device is an ideal solution for many different electronic applications.
