Introduction

Trimmer potentiometers, also known as trimmers, trim pots, variable resistors, or adjustable resistors, are small electronic components that provide a variable resistance to control the output of an electronic circuit. 3057Y-1-202 is an example of a trimmer potentiometer in a TO-220 package.

Application Field and Working Principle

Trimmer potentiometers are used in a wide variety of applications, ranging from calibrating radios to adjusting the speed of a motor. The 3057Y-1-202 is designed for use in medical and military applications. It can also be used to fine-tune circuit parameters, for example, a motor regulating device, to accurately level out and control the working voltage and power of the motor. The 3057Y-1-202 is a three-terminal trimmer potentiometer with a resistance range of 0 to 200 ohms. It has three terminals named S (side), C (center), and C2 (center2). The S terminal is the common terminal and the C and C2 terminals are the adjustable ends. When the C and C2 terminals are connected, the resistance between S and C/C2 is 0 ohms or the minimum resistance. When the C and C2 terminals are adjusted, it varies the resistance between the S and C/C2 terminals up to a maximum of 200 ohms. The resistance value can be adjusted in order to get the desired output voltage value.The 3057Y-1-202 is designed to provide reliable performance under harsh environmental conditions. It can operate in temperatures ranging from -55°C to + 125°C, and can also handle shocks and vibrations of up to 2,000g. It is also corrosion resistant and moisture resistant, making it well-suited for use in high-moisture environments.

Conclusion

The 3057Y-1-202 trimmer potentiometer is a versatile component that can be used in a wide range of applications. Its resistance range of 0 to 200 ohms makes it ideal for fine-tuning circuit parameters, and its robust design makes it well-suited for use in harsh environments. By adjusting the C and C2 terminals, the resistance between S and C/C2 can be varied up to a maximum of 200 ohms, allowing the user to achieve the desired output voltage value.
