Adjustable power resistors, such as the D225K250E, are devices that provide adjustable resistive power paths in electric circuits. The device\'s power rating is 225 mW and the resistance value can be adjusted up to 250 ohms.
The D225K250E is a three-terminal resistor with the terminals marked as A, D and E. The resistance value of the component can be adjusted externally through a varying current from A to D, enabling the device to perform power level control functions in various types of electrical circuits. The adjustment of the resistance is achieved by the control current flowing through a potentiometer controlled by the external current.
The working principle of the device is simple. A variable voltage is applied across terminals A and E, which produces a controlled current, from A to D, through which the device adjusts its resistance. The control current varies from zero to a maximum level, determined by the applied voltage and the maximum resistance value. As the control current increases, the resistance of the device decreases, and vice versa.
The D225K250E is typically used for temperature control circuits, current limiting circuits, and as a potentiometer for audio signal control. In temperature control circuits, the adjustable current is used to adjust the resistance of the device to control the rate at which the temperature rises or falls. In current-limiting circuits, the adjustable current is used to limit the current flow in the circuit.
In audio signal control applications, the adjustable current is used to adjust the resistance of the device to control the audio signal amplitude. The device can also be used as a variable attenuator or noise filter in audio signal circuits.
The D225K250E is also suitable for use in high frequency circuits, such as RF amplifiers, where its adjustable resistance can be used to set the amplifier gain. It can also be used for fine-tuning oscillator circuits. The device has a wide range of capabilities and is useful for many different circuit applications.
