Trimmer Potentiometers

A trimmer potentiometer, also referred to as a trimpot or trimmer, is a type of variable resistor with a movable contact that is adjusted by a small tool when set. Trimmer potentiometers are used for calibrating or fine-tuning circuits, as they offer greater precision than a standard potentiometer.

The3339H-1-104LF trimmer potentiometer is a high precision, low profile, trimmer potentiometer. It has an adjustable resistance of 100 ohms with a tolerance of 5%. It is made of high-reliability cermet material and features an operating voltage of 0.3V to 10V. The actuator rotates and features 1 turn of adjustment with a detent click. It is available in a lead-free, SMD option and a 12.3mm x 7.62mm footprint.

Application Field

The3339H-1-104LF trimmer potentiometer is an ideal choice for applications with limited space and where space savings are important, such as medical equipment, remote controls, test equipment, computer peripherals, automotive electronics, security systems, and more. It is also suitable for applications that require high accuracy or repeatability like test and measurement equipment, and audio and audio components.

Working Principles

The3339H-1-104LF trimmer potentiometer operates on a basic electrical principle. When the wiper arm is rotated, the contact between the wiper and resistor body changes. This resistance then affects the output voltage of the device, enabling adjustment and fine-tuning. This general principle applies to all types of trimmer potentiometers.

The3339H-1-104LF trimmer potentiometer has a particularly advantageous combination of features which make it a good fit for a wide range of applications. Its small size, lead-free options, and high reliability propel this trimmer potentiometer to the top of the list in many user-maintenance scenarios, as the superior precision and small footprint make this trim pot ideal for space-restricted applications.

The3339H-1-104LF trimmer potentiometer is an excellent and reliable choice for such applications. With its adjustable resistance of 100 ohms with a tolerance of 5%, the3339H-1-104LF enables precise and repeatable fine-tuning or calibration, as well as adjustment and resolution in short-length applications. While there are other trimmer potentiometers available that are larger and less precise, few can match the precision and space-savings of the3339H-1-104LF.
