Trimmer Potentiometers

A trimmer potentiometer, also known as a trim pot, is a variable resistor which is used to adjust the electrical output of a circuit. This component is designed to provide easy adjustment for many electronic applications. Trimmer potentiometers can be found in a wide range of electronic devices from radio receivers to guitar pickups. Most trimmer potentiometers have an adjustable resistance range between 10KΩ to 1MΩ, though some can range up to 10MΩ. Trimmer potentiometers are typically used in circuits that require fine adjustments, where larger variable resistors prove to be too bulky or uncompensated. For example, if a circuit requires obtaining a precise signal readings as small as 5mA, then a trimmer potentiometer is required because larger components cannot offer such precise adjustment. In addition, since trimmer potentiometers can cover such a wide range of resistance such as 90PR20KLF, they can provide a much broader range of adjustability compared to other components. Trimmer potentiometers are cylindrical components, typically with the diameter of a quarter of an inch, and with length ranging from 1/16” to 1/4”. They are usually made of plastic or ceramic, with the exception of high temperature units, which are typically made of metal housing. The housing has three terminals: two stationary terminals and a rotating contact, known as the wiper. Depending on the type of trimmer used, the wiper may be adjusted with a slotted screwdriver or turning trim tool such as a thumb wheel. The working principle of a trimmer potentiometer is similar to a standard potentiometer. As the wiper is rotated, it creates a different resistance in the circuit, which is represented by a voltage output. The resistance, or “R” value, is calculated by dividing the potentiometer’s full-scale voltage (V∞) by the total resistance (R∞). For example, a trimmer potentiometer with a 90PR20KLF application field has a resistance of 20KΩ when the wiper is turned to its maximum point. Trimmer potentiometers are common components in circuits due to their high resolution and wide adjustable range. They provide precise control and easy adjustment for applications that require an accurate voltage output or current setting. Trimmer potentiometers are an excellent choice for precision electronic applications, offering adjustable resistance from 10KΩ to 1MΩ.
