The AHA80AJB-56R resistor is a chassis-mount device built to provide the maximum wattage with minimal heat dissipation. This resistors offers design flexibility and long-term reliability, in addition to fantastic semi-dynamic characteristics. The AHA80AJB-56R resistor is perfectly suited for a wide variety of applications, including automotive, industrial, and military circuit designs, and is highly recommended for use in almost any service, where strong heat dissipation is important.

The AHA80AJB-56R is a precision, metal element resistor capable of dissipating power up to 120 watts per square centimeter. Its standard body configuration - 1.535 × 2.916mm (5/16 × 5/8in) - allows the device to mount in almost any type of chassis. The device offers an incredible immediate power rating of 80W at 25°C, and increases its power range up to 120 watts at 85 °C. It also features an impressive dynamic characteristics of maximum voltage breakdown for every decade of frequency up to 1MHz, and no more than 0.2% total harmonic distortion.

The working principle of the AHA80AJB-56R is based on the heat dissipation of the resistor’s resistive element. The metal element utilizes the Joules-Lenz law, in which a current passing through the resistive element dissipates power as heat. This heat is dissipated through a combination of the heat sink area and the surrounding environment, creating higher power densities at higher temperatures. The resistor is designed to operate at a wide range of temperatures and can handle up to 10 times the rated power for short periods.

The AHA80AJB-56R has a simple yet effective design, with an advanced skin effect to minimize the power and ensure reliability. It also features low inductance, superior surface mount design, and an optimized heat sink that dissipates heat while protecting the internal elements from the heat generated by the surrounding environment. The advanced design also minimizes the thermal efficiency of the resistor, yielding increased power efficiency and power densities.

The AHA80AJB-56R is an excellent choice for a wide range of applications, including automotive, industrial, and military circuit designs. The AHA80AJB-56R also has an extensive temperature operating range from -55? to +105?, making it an ideal choice for use in extreme temperature environments. With its high power dissipation and long-term durability, the AHA80AJB-56R is a reliable and cost-effective chassis-mount resistor solution.
