Trimmer Potentiometers

Trimmer potentiometers, also known as trimpots or trimmers, are an essential form of variable components used in the electronics and electrical industries. They are typically used when the exact potential of an individual circuit must be precisely adjusted, as in specific types of radios, medical and industrial controls, and avionics. Trimmer potentiometers are typically designed to be used as adjustable resistors, trimmers, adjustable voltage dividers, instrumentation amplifiers and error amplifiers. They are also commonly used to tune amplifiers, oscillators, and other circuitry applications.

3306W-1-253 Application Field and Working Principle

The 3306W-1-253 is an example of a trimmer potentiometer created by Bourns for use in critical applications. This product is designed to provide a reliable, general-purpose, adjustable resistor element. It is typically used in the manufacture of oscillators, audio amplifiers, voltage regulators, and other circuit designs.

The 3306W-1-253 operates within a 10% tolerance and provides a tested, standard form factor for potting and surface mount applications. This is achieved by its available package forms including a 90º 8-pin DIP, open-frame, and a stainless steel body. It also features a wide-range temperature coefficient of 75-125 ppm/deg and provides excellent linearity and repeatability.

The 3306W-1-253 is a one-turn wire-wound trimmer potentiometer. It has a wide resistance range from 0.5 kilohms to 500 kilohms. It features a single-ganged design that offers a more uniform adjustment. The resistance of the potentiometer is adjusted by turning the shaft at the end of the potentiometer with the aid of a screwdriver or other tool. The potentiometer can be adjusted from the minimum to the maximum resistance with every turn of the screw.

The 3306W-1-253 provides reliable performance in a variety of critical applications. It is designed to ensure the highest levels of accuracy and dependability in applications as varied as industrial control equipment, radio communication systems, audio amplifiers, and voltage regulators. It is a useful, durable and reliable device, able to provide precise resistor adjustment in a variety of applications.
