Introduction

Chassis mount resistors are defined as resistors that are designed to be installed in a chassis or other surface mount systems. It is important to note that they are not designed for hand-held use or for soldering on a circuit board; instead, they are designed to be firmly mounted (generally using a slide-in type of mount) directly on the chassis or PCB board of an electronic system. The AHA500FB-19R6 is one such chassis mounted resistor that is designed for a range of uses and applications.

AHA500FB-19R6 Specifications

The AHA500FB-19R6 is a fixed single-turn 5 watt power resistor featuring a steel-bonded electrode structure for superior corrosion resistance. It is designed to be mechanically, thermally, and electrically robust, and features a 0.500 inch body size and 19 ohm resistance value. It has a tolerance of up to 5% and its temperature coefficient is 150ppm/°C.

AHA500FB-19R6 Applications

The AHA500FB-19R6 is a versatile resistor that can be used in a variety of applications such as automotive, lighting, power supplies, and consumer electronics. It can be used in applications that require high-power and high-temperature performance. Specifically, it is well-suited to applications requiring a high-wattage power resistor with superior thermal, mechanical, and electrical characteristics, such as a motor drive or a boost converter.

AHA500FB-19R6 Working Principle

The AHA500FB-19R6 is a fixed single-turn 5 watt power resistor and it works by resistively absorbing energy from the incoming electrical current. Essentially, it “resists” the current and reduces its power, thus providing an appropriate level of protection for other devices. This is done by converting the incoming electrical energy into heat energy, which is then dissipated into the surrounding environment. The resistor’s resistance value and wattage determine how much of the incoming electrical current can be resistively absorbed.
