Trimmer Potentiometers

3057P-1-500 is a trimmer potentiometer. It is an adjustable electrical component composed of a resistive element and a sliding contact, commonly called a wiper. These components are used to control the current of an electric circuit, usually for measuring or regulating level such as voltage, current or power.

Application Field

3057P-1-500 is designed to form a preset resistor in a circuit controlled by the position of a movable contact. It is used in various application fields, including medical instrumentation, data acquisition systems, automatic test equipments, experimental control systems, and industrial automation. It is also used in audio equipment to adjust the volume or sound. It is used with remote control of devices like TVs, radios, stereos, and as an adjustable voltage divider.

Working Principle

3057P-1-500 working principle consists of a resistor with a fixed area over its entire length. A wiper moves along the resistor to make contact with segments of varying resistance. The resistance value of the potentiometer is determined by the position of the wiper on the resistor. When the wiper is at one end of the resistor, its resistance is at a minimum and increases as the wiper moves along the resistor. When the wiper is at the other end, its resistance is at a maximum.

The 3057P-1-500 has a total resistance range of 500Ω and resistance tolerance of ±20%. The power rating of the potentiometer is 0.1Watt and the dielectric strength is 100V. The operating temperature ranges from -55°C to +125°C.

The 3057P-1-500 can be used with various types of controls such as a rotary knob, a lever handle or a slide control. It can also be used in a variety of circuits depending on the application.

In summary, the 3057P-1-500 trimmer potentiometer is an adjustable electrical component used in a variety of applications. Its resistance value is determined by the position of a wiper and it has a total resistance range of 500Ω and a power rating of 0.1Watt. The operating temperature ranges from -55°C to +125°C and it can be used with various types of controls.
