Trimmer Potentiometers

Trimmer Potentiometers (also known as trimmer pots or trimpots) are variable resistors that use a three terminal configuration with a sliding contact, an adjustable resistance element, and a mechanical support. They are typically designed for use in professional, industrial, and consumer applications where precision control of a relatively low current is required. Trimmer Potentiometers are often used in audio circuits, power supplies, signal processing circuits, and other high performance electrical circuits.

25SR5KLF Application Field and Working Principle

The 25SR5KLFTrimmer Potentiometer is a three-terminal, variable-resistance device designed for use in high performance circuits such as audio, power and signal processing. The 25SR5KLF Trimmer Potentiometer features a top-adjustable slider to set the resistance value. It has a nominal resistance of 5KΩ and a rotational travel of 270° ± 6°. The 25SR5KLF is designed for use in professionally soldered and soldered-in-place applications.

The working principle of the 25SR5KLF Trimmer Potentiometer involves the use of a slider that is movable along the three tracks, and the change in resistance is proportionate to the displacement of the slider. The slider position is determined by the rotation of an external adjusting knob affixed to the trimmer potentiometer, and this is what allows the operator to adjust the resistance value.

The 25SR5KLF Trimmer Potentiometer can be used in a variety of applications, including amplifier circuits, filter circuits, signal conditioning circuits, and signal processing circuits. It can also be used in power supply circuits, speaker circuits, and automotive audio systems. In addition, this device can be used in voltage regulation circuits, voltage divider circuits, and impedance circuits.

The 25SR5KLF Trimmer Potentiometer is ideally suited for high-performance applications requiring precise control of resistance. This precision-tuned device features a tight resistance tolerance of ±10%, and an operating temperature range of -40°C to +85°C. Furthermore, the 25SR5KLF Trimmer Potentiometer is RoHS compliant and UL and CSA listed for safe operation.
