Trimmer Potentiometers
EVM-AJGA00B25 is a trimmer potentiometer, which is an electronic component used to adjust the resistance of a circuit. It is usually used in applications such as audio equalizers, analog television systems, amplifier circuits.
Application Field
EVM-AJGA00B25 is a trimmer potentiometer that is designed to have a wide resistance range so it can be used for a variety of applications. It is commonly used in electronic circuits as an adjustable resistor. The resistance of the device can be adjusted with a screwdriver, making it a convenient option in applications where precision tuning is required. It can be used to adjust the frequency response of an audio system, the color of a television picture, or to adjust the gain of an amplifier. It is also useful for adjusting the cutoff frequency of notch filters or for adjusting the set points of switched circuits such as limiters and comparators.
In addition, the EVM-AJGA00B25 trimmer potentiometers are also used as a calibration tool. They are often used to adjust the values of components such as capacitors, inductors, and resistors in a given circuit. This allows the circuit to be adjusted to optimize its performance and compensate for variations that may have arisen during the manufacturing process.
Working Principle
Trimmer potentiometers work by varying the resistance of the circuit from a minimum to a maximum value. The resistance is changed by adjusting the position of a wiper contact on the track of the potentiometer. The wiper contact is connected to a spindle which is turned with a screwdriver or a precision screwdriver.
When the spindle is turned, the wiper contact moves along the track of the potentiometer. As the contact moves across the resistance track, the resistance of the circuit increases or decreases depending on the direction the wiper contact moves. Once the desired resistance is found, the screwdriver can be released and the trimmer will stay adjusted in its new position.
EVM-AJGA00B25 trimmer potentiometers are also adjustable using digital methods. This can be done by connecting the device to a computer with digital control signals. The computer can then be used to control the resistance value of the trimmer over a wide range of values. This is a convenient way to adjust the trimmer without requiring physical access to the device.
