AHA80AFB-56R

Chassis Mount Resistors

Chassis mount resistors are an essential component to any electrical system, offering both electronic and thermal protection to a wide range of wiring and system components. These types of resistors offer several advantages, the most important being that they are capable of withstanding extreme weather conditions, and can handle large operating temperatures. The AHA80AFB-56R is a chassis mount resistor specifically designed to meet the demand for high power, high current solutions. This resistor is rated up to 80A with a working temperature of -55°C up to 175°C, with a resistance tolerance of 0.5%.

Application Field

AHA80AFB-56R is typically used in automotive applications, such as controlling relay coils, starter circuits, and energy management systems. It is also suitable for commercial systems, such as robotics or industrial controllers. Other applications include power supplies, electronic meters, and medical equipment. The resistor’s high current rating also makes it a viable alternative for audio applications, as it can handle the large current draw associated with amplifiers.

Working Principle

Chassis mount resistors work in the same manner as other types of resistors by dissipating power in the form of heat. This occurs when a current is passed through the component, where it is resisted by the material of the resistor. This resistance causes the resistor to become hot, and the temperature of the resistor can be tripled for each watt of power dissipated. By using a heat sink and proper thermal management, the AHA80AFB-56R can be used safely in high temperature environments.

The component’s thermal overload protection feature is an added layer of safety. The protection feature limits the current that can be passed through the resistor, which in turn helps prevent potential overheating. The resistor is designed with a built-in fuse, so if the current draw exceeds the maximum threshold, the built-in fuse will be triggered, stopping the flow of current and protecting the resistor from damage.

Overall, the AHA80AFB-56R is an extremely versatile, high power chassis mount resistor that can withstand high temperatures and heavy current draws. Its thermal protection feature makes it ideal for use in industrial and automotive applications, as well as other high current equipment. By ensuring proper installation and maintenance, this resistor can offer long-lasting protection for various electrical systems.
