ST42ETB504

Trimmer Potentiometers represent a wide range of device types and functions, including linear and rotary components that allow for a variety of selectable positions or levels in a circuit. ST42ETB504 is widely used in many applications and can be used to adjust the voltage output, change the frequency of an oscillator, set reference voltages, and various other analog tasks. This article will discuss the application field and working principle of the ST42ETB504.

General Features

The trimmer potentiometer ST42ETB504 is a 4-terminal device that has an output voltage of 0.3V to 5.2V. It is designed for operation in areas where tight tolerances are required, and with an input current of 1mA to 7mA, it can handle larger currents than other types of trimmer potentiometers. Also, the device is hermetically sealed, making it ideal for use in a variety of applications and environmental settings.

Application Field

The ST42ETB504 trimmer potentiometer can be applied in a variety of situations where precise adjustments in voltage output, frequency, or other analog functions are necessary. Some examples include the following:

• Adjust the voltage output of a voltage regulator
• Change the frequency of an oscillator
• Set reference voltages
• Set the resistance of an adjustable load
• Provide accurate adjustments in radio and television circuits
• Provide compensation in analog circuits
• Adjust sound levels in recording equipment
• Set regulation in cameras

Working Principle

The ST42ETB504 trimmer potentiometer allows for a range of adjustment by changing the resistance of the device. It is designed such that the resistance is adjustable in a linear fashion with each step giving an increase or decrease in resistance. To adjust the resistance of the device, the internal wiper is used to move the wiper contact along the resistor. This wiper contact is connected to the output terminal of the device and will output the adjusted voltage.

The adjustments made to the ST42ETB504 can be done in small increments, allowing for precise adjustments in the output voltage. This is done by varying the resistance on the wiper contact as it moves along the resistor. As the contact moves along, usually in the form of a circular motion, the output voltage will increase or decrease with each step. The range of adjustments depends on the number of divisions set on the wiper contact, which can be set in 5 or 15 steps.

Conclusion

In conclusion, the ST42ETB504 trimmer potentiometer is a versatile and adjustable device that can be used for a variety of analog functions. It has an output voltage of 0.3V to 5.2V, and with an input current of 1mA to 7mA, is suitable for a variety of applications. The device is hermetically sealed, and its internal wiper contact can be used to move the contact along the resistor, allowing for precise adjustments in the output voltage.
