ST5ETW102 Potentiometers, Variable Resistors

Trimmer Potentiometers

A Trimmer Potentiometers is a type of rotational electric potentiometer. This device comprises of a rotary shaft that is adjusted by a knob with a pin along with a conducting track that is connected to the 2 terminals. The device can be used in various applications such as controlling audio volume, controlling gain in electronic circuits, and for other applications as a substitute for a potentiometer if space is an issue.

The ST5ETW102 is a popular trimmer potentiometer due to its small size and low cost. It features a 10 turn, 10 kΩ ceramic element attached to a metal platform that helps reduce vibration and is resistant to shock. The potentiometer works by connecting the two terminals to a voltage source and manipulating the knob to adjust the position of the wiper. This will cause the resistance of the track to be changed, creating an output that corresponds to the position of the knob on the potentiometer.

The ST5ETW102 is suitable for various applications such as audio volume control, controlling gain in electronic circuits, and as a substitute for a potentiometer when space is limited. It is also used to control the power output of various motor control devices. The device is capable of providing accurate readings and can withstand temperatures ranging from -40°C to 125°C.

In addition, the ST5ETW102 is also popular for its ease of use. It features a strong spring that provides excellent repeatability and enables the user to make precise adjustments in situ. The device is sealed to prevent dust and moisture from entering, and is designed with a shaft protection to reduce the possibility of breakage. The device also has an anti-drift function which eliminates false readings from occurring due to temperature changes.
