Chassis Mount Resistors: HS10 120R J Application Field and Working Principle

Resistors are electronic components used to reduce and control the level of electrical current as it flows through a circuit. They come in numerous sizes and types, with one of the most commonly used types being chassis mount resistors. The HS10 120R J resistor is one such chassis mount resistor and this document will discuss its application fields and working principles.A chassis mount resistor is designed to be easily mounted on the inside of more robust enclosure or chassis, such as those found in professional audio systems, communication systems, and medical equipment. HS10 120RJ resistors are designed to be able to withstand long-term operation in a harsh environment. This allows them to be employed in such application fields as industrial, aviation, military, and medical technologies.

Construction Features

HS10 120R J resistors feature an encapsulated construction of a high-performance thermoset plastic encapsulation and resistor element, and then molded and formed into a compact package for a high degree of environmental and electrical performance. The external package also allows for complete impregnation and electrical insulation of the resistor element, providing superior mechanical resistance within the application environment. These resistors also feature a superior mounting design that ensures maximum connection stability during vibration or shock.The standard HS10 120RJ package consists of a spun-and-weld nickel-plated metal contacts, while the UL version is constructed with tin plated contacts. Additionally, they feature an extruded 17 mm lead screw with multiple thread turns that reaches into the resistor’s element area, and Clinch nuts are used in the UL version and standard casing. The resistor elements are usually of thick-film or thin-film designs, and they are resistance welded with either sapphire or ceramic to prevent resistance shift.

Working Principle

The working principle of a resistor is based on Ohm’s law, which states that “the voltage dropped across a resistor is proportional to the current through it.” This means that when an electric current passes through a resistor, some of the energy is converted to heat, reducing the electric current flowing through it. The resistance value of a resistor determines the amount of current flow reduction. HS10 120RJ resistors feature a resistance value of 120 ohms, which means they are able to reduce the flow of current by this amount. The amount of heat generated by the resistor depends on the resistance value and the amount of current flowing through it. As the current flow increases, so will the amount of heat generated by the resistor. HS10 120RJ resistors are designed to dissipate a maximum of 180mW of power, meaning that they should not be used in applications that require more power than this.

Conclusion

HS10 120RJ resistors are robust chassis mount resistors that are ideal for harsh environment applications, such as those found in industrial, aviation, military, and medical technologies. They feature a resistance value of 120 ohms, which limits the amount of current that can flow through the resistor, and they are also designed to be able to dissipate a maximum of 180mW of power. They are designed to ensure maximum connection stability during vibration or shock, and feature an external package that provides complete impregnation and electrical insulation of the resistor element.
