IntroductionThe AHA25AFB-221R is a chassis mount resistor. It is designed to provide electrical control and limit the current that passes to the device. The device is durable, reliable, and suitable for harsh environments. The chassis mount resistor is available for a wide range of applications, including high-power systems, DC power systems, and industrial applications.
Design and Features
The AHA25AFB-221R chassis mount resistor is a through-hole, surface-mount device. It features a durable and reliable ceramic core, with solderable electro gold plating. The device has a thick-film resistive element, and is rated for 10A continuous current. The device has a maximum voltage between terminals of 650V, and a maximum resistance of 0.1 ohms. The resistor has a dielectric strength of 250V, and a maximum operating temperature of 250°C. The resistor is RoHS compliant, and is UL certified. The device is available in a variety of sizes and form factors, including DIP, SMD, and MELF packaging.
Applications
The AHA25AFB-221R chassis mount resistor is suitable for a wide range of power system applications, including high power systems, DC power systems, and industrial applications. It is designed to provide electrical control and protect against over-current. The device can be used in motor control and automation applications, as a current limiter and voltage regulator. The device is also suitable for military and aerospace applications, where performance and reliability are critical.
Working Principle
The AHA25AFB-221R chassis mount resistor works based on the principle of Ohm’s law. When current is applied to the device, the electrical resistance of the resistor will convert a portion of the energy into heat. This heat is then dissipated to the surrounding environment, thereby limiting the electrical current passing through the device. The amount of heat dissipated will depend on the magnitude and duration of the applied current, as well as the size and type of resistor used. The device can be used in applications such as motor control, voltage and current regulation, and circuit protection, where it can provide electrical control and prevent damage to the circuit by limiting current.
