EVM-3WSX80B12 Potentiometers, Variable Resistors

Trimmer Potentiometers are important components in electronic circuits, providing a convenient and reliable way to adjust resistances in a circuit. The EVM-3WSX80B12 trimmer potentiometer is a single-turn trimmer with a wide range of applications.

The EVM-3WSX80B12 is a carbon film trimmer potentiometer with a nominal resistance of 8 ohms. It has an overall height of 9.5 mm and a maximum voltage rate of 1 watt. It is made of high-quality plastic and comes in two different mount styles: through-hole or surface mount. This trimmer is typically used for balancing resistances in audio circuits.

The basic operating principle behind the EVM-3WSX80B12 is simple. It is composed of three main parts: a carbon film resistor, a rotary shaft and a knob. When the knob on the potentiometer is turned, it rotates the rotary shaft, which in turn turns the wiper arm of the carbon film resistor. This in turn changes the resistance of the circuit by increasing or decreasing the contact between the wiper arm and the resistor.

The EVM-3WSX80B12 is a versatile trimmer potentiometer that can be used in a wide range of applications. It is often used in audio controls, such as volume control, tone control, balance control, and frequency selectors. It is also commonly used as various types of sensors, such as thermistor sensors, strain sensors, and force sensors. In addition, it can also be used in motor control circuits.

The EVM-3WSX80B12 trimmer potentiometer is a reliable and cost-effective option for controlling and adjusting resistances in electronic circuits. Its compact size and high power rating make it well-suited for a variety of applications. With its wide range of uses and reliable performance, it is an excellent choice for any circuit project.
