Adjustable power resistors serve a wide range of applications across many different industries. They are used to limit, tap, control, and measure power in both AC and DC circuits. These power resistors are typically used in AC power supplies, power conditioners, and test instrumentation.The D25K4K5E is a special type of adjustable resistance with four terminals designed to be adjustable between 0 and 5kΩ. It operates in two regions of operation: linear region and non-linear region. Linear region allows smaller swings in resistance, while non-linear region enables larger adjustments.In linear region, Joule heat is dissipated over the entire range of stress, which means the dissipated power will remain constant throughout the range. On the other hand, in non-linear region the Joule heat will dissipate within a limited period of time.The D25K4K5E is a dual emitter type adjustable resistor, which means there are two emitters connected to each other through a common terminal. The common terminal is connected to the power source and the other two terminals are connected to the load. The powerful DC voltage applied to the common terminal is responsible for controlling the amount of resistance between the two emitters.In linear region only a few voltage levels are necessary to adjust the resistance across the two emitters. Increasing the voltage applied to the common terminal will cause the voltage across the two emitters to increase linearly, resulting in increased resistance. On the other hand, in non-linear region more voltage levels are required to achieve the same result.The D25K4K5E also includes a temperature compensating feature. When the external environment temperature increases or decreases, the resistance value changes to keep the internal temperature within its specified operating range. This feature allows the device to remain stable even in extreme temperature conditions.The D25K4K5E is suitable for a wide variety of applications, such as energy-saving lamps, solar/LED lights, energy metering devices, monitors, etc. It is able to provide precise resistance value with high accuracy. As a result, the device is also becoming more and more popular in other industries, such as automotive, consumer electronics, medical, communication and industrial automation.In summary, the D25K4K5E adjustable power resistor is well suited for use in many different applications. It is a reliable device with great performance and accuracy. Its temperature compensation feature ensures that it remains stable even in harsh environmental conditions.
