Chassis Mount Resistors - HSA1020RF

The HSA1020RF is a type of chassis mount resistor designed for high-power applications and a wide range of temperatures. It is constructed from aluminum oxide ceramics and features a robust, reliable design. Its low profile and resistance range make it well suited for both commercial and industrial applications.

Applications

The HSA1020RF is typically used in power management applications, as a current or voltage limiter, or as a shunt resistor. It’s well-suited for applications such as power line balancers, LED lighting systems, battery charging circuits, automotive power supplies, switches, and power supplies.The HSA1020RF can also be used in precision measurement and control applications, such as medical instrumentation, scientific instrumentation, precision timers, transistor testing devices, and power monitors. Its low power dissipation and constant performance make it an ideal choice for these types of applications.

Working Principle

The HSA1020RF works by dissipating electrical energy as heat in order to limit current or voltage. It has a fixed resistance value and is usually wired in series with the circuit. When the current exceeds the maximum value the resistor can handle, the resistor will absorb the extra current, decreasing the voltage in the circuit and limiting the current. The resistance value of the resistor is determined by the material composition and construction. Aluminum oxide ceramics are the core material used in the HSA1020RF. The material composition also determines the temperature coefficient of resistance, which is the ratio of change in resistance relative to the change in temperature. This allows the resistor to maintain its resistance and performance over a wide range of temperatures.

Advantages

The HSA1020RF offers several advantages over other types of resistors. The low-profile design allows it to fit into tight spaces. Its high-temperature performance and adjustable voltage are also beneficial for applications which require high-reliability performance in extreme temperatures.The HSA1020RF has a low power dissipation compared to other resistors, making it ideal for applications that require precise voltage or current control. Additionally, the resistance value of the resistor is not affected by voltage or current drops, ensuring stable and reliable performance.Overall, the HSA1020RF offers a robust and versatile chassis mount resistor solution for a wide range of high-power applications. Its low profile, adjustable voltage, and high-temperature performance make it an ideal choice for applications requiring precise voltage and current control.
