Trimmer Potentiometers

Potentiometers are variable resistors used to measure or adjust an electrical signal. The most common form of the potentiometer is the rotary potentiometer, or “trimmer”, which uses a rotary knob to adjust the resistance. The 89WR10KLF trimmer potentiometer is a 10 kOhm device with a single turn rotary adjustment.

Application Field

The 89WR10KLF trimmer potentiometer is ideal for automotive, consumer electronics and instrumentation applications due to its low cost, accurate resistance range, and small size. It is used in a variety of applications including engine control ventilation systems, vehicle interior lighting, and sound systems.

The 89WR10KLF can also be used in consumer electronic devices such as audio amplifiers, cellular phones, computers, and other portable devices. It is also used in medical devices such as glucose monitors, heart rate monitors, and blood pressure monitors. It is also used in instrumentation applications such as vibration measuring equipment, laboratory equipment, and industrial test equipment.

Working Principle

The 89WR10KLF trimmer potentiometer works by adjusting the resistance of the device. By turning the rotary knob, the internal contacts move closer or farther away from each other, thus changing the resistance between them. This is used to measure, or adjust, the current or voltage of an electrical signal.

The 89WR10KLF can be adjusted in either direction. It has a wide range of resistance values, from zero to 10 kOhms, and a linear adjustment range of 260°. It is also capable of withstanding 4kV of shock voltage, and is designed to operate in temperatures ranging from -35°C to 125°C.

The 89WR10KLF is a reliable and accurate trimmer potentiometer that is small in size and low in cost, making it an ideal choice for a variety of applications. It is designed for long term reliability and performance in harsh environments, and can withstand shocks or thermal changes making it suitable for use in a variety of industries.
