3057L-1-101M

Trimmer potentiometers are a type of electrical component used to provide a variable level of resistance in circuits. Many applications, from simple volume control potentiometers found on radios to precision calibration potentiometers, use trimmer potentiometers. The 3057L-1-101M is a trimmer potentiometer and it is found in a wide variety of applications.

Description

The 3057L-1-101M is a single-turn, miniature, trimmer potentiometer with a maximum resistance of 100 ohms. It is designed for through-hole mounting and can be soldered onto a printed circuit board. It has a compact, square-shaped body measuring 2.4mm x 3mm and a height of 1.4mm above the board. It is rated for 125mW power handling and it has solder-lug terminals to connect it to a circuit.

Application Field

The 3057L-1-101M trimmer potentiometer is used in many applications due to its small size and wide range of capabilities. It is suitable for fine adjustment in industrial control, home audio, digital audio equipment, automobile audio and portable electronics. The 3057L-1-101M is also widely used in medical equipment, test and measurement equipment, computer peripherals, consumer electronics and instrumentation. It can even be used in harsh industrial settings such as automotive and aerospace manufacturing.

Working Principle

A trimmer potentiometer works on the principle of a variable voltage divider. The voltage entering a trimmer is divided by the potentiometer\'s resistance. The output voltage is the ratio of the input voltage and the resistance. This output voltage can then be adjusted with the potentiometer\'s wiper arm, allowing the user to set the desired output voltage. The 3057L-1-101M is a single-turn potentiometer which means only one full rotation of its knob is required to adjust its resistance from minimum to maximum. This makes the 3057L-1-101M ideal for applications requiring accurate and precise adjustment.

Conclusion

The 3057L-1-101M is a single-turn trimmer potentiometer which is suitable for a wide range of applications. Its small size, wide range of capabilities, and precise adjustment make it an attractive option for many designers. It is found in many consumer electronics, instrumentation, and industrial control applications. By dividing the input voltage with its adjustable resistance, it is able to produce a variable output voltage.
