The AHA25AFB-46R4 is a chassis mount resistor, which is a type of electronic component used for regulating and controlling the amount of electricity flowing through a system. This particular resistor is designed to reduce the electrical current, lower voltage and dissipate heat in a variety of applications. Its optimal working temperature range is between -40°C and +150°C. This paper will discuss the application field, working principle and key features of the AHA25AFB-46R4.

Application Field

The AHA25AFB-46R4 resistor is suitable for both commercial and industrial applications because of its ability to withstand a variety of environmental conditions. It is used in motor control, automotive, railway control, traction systems, power supplies, lighting, appliances and other high power circuits. Additionally, the component is also used in applications which require variable and adjustable resistances such as AC/DC circuits, current limiters, bypass circuits and resistive dividers.

Working Principle

The AHA25AFB-46R4 operates based on Ohm’s Law, which states that the current flowing through a resistance is inversely proportional to the voltage applied across the terminals. Then, the chassis mount resistor uses this law to regulate the current that flows through the system. The current is controlled by the value of the resistor, which is measured by its resistance rating in Ohms. The resistor works to lower the voltage and dissipate heat generated from the system.

Key Features

The AHA25AFB-46R4 delivers impressive performance results, with a resistance tolerance of 5% and an operating temperature range of -40°C to +150°C. This chassis mount resistor has a compact footprint of 22.17mm x 10.41mm x 11.20mm and a low-profile design which makes it easy to install in tight spaces. Additionally, the resistor is compliant with IEC safety standards and comes with a UL rating of PL-1000V.

Overall, the AHA25AFB-46R4 is an excellent choice for applications that require variable or adjustable resistances and current control. Its many features, such as a low profile design and a wide temperature range, make it well-suited for power supply and motor control systems in both commercial and industrial settings.
