Frequently asked questions

What Is a Trimmer Potentiometer?

To modify the resistance of an electric circuit, you can use a potentiometer, which has three prongs. A resistive element has two ends attached to the terminals, and the third terminal is connected to a sliding contact, known as a wiper, that moves across the resistive element. The potentiometer divides the current through a changeable resistance. The wiper position sets the resistance ratio of the potentiometer’s resistive element, two resistors connected in series. To adjust the output voltage, provide a reference voltage across the terminals and move the wiper.

A potentiometer, or pot for short, is a measuring instrument. Typically, a rotating potmeter with a single turn is what you’ll find in a home. There are numerous uses for pots with a logarithmic taper, including controlling the volume of an audio system. Cermet, Carbon composition, wirewound, conductive plastic, and metal film are only some of the materials that can be utilized to make a potentiometer.

What does a trimmer resistor do?

Trim pots are adjustable potentiometers used to fine-tune and calibrate electronic circuits. After being manufactured, these trimmer resistors are frequently utilized for the first round of adjustments in the calibration process.

What is the purpose of the 10k trimmer?

The picture of a 10k Variable Resistor setup on a vertical PCB can be seen to the right. The resistance of a trimmer potentiometer, a variable resistor having three terminals and a screw that can be turned to adjust the resistance, can be adjusted as needed with the intent of changing the voltage, current, and other elements of an electrical circuit.

Characteristics

● Taper

The taper describes the correspondence between mechanical position and resistance in a potentiometer. The most frequent types of taper are linear taper and logarithmic(audio) taper. If you want to learn more, check out the page I made only for the potentiometer taper.

● Marking codes

“100k” for a 100 k potentiometer is a frequent label. The SMD resistor coding-style approach of using three digits to denote values is sometimes employed. The first digits in this system represent the value, while the last digit represents the multiplier. For instance, the binary representation of 1 kilohertz is 102; hence 10 x 102 equals 1 kilohertz.

A potentiometer’s taper is typically denoted by a letter. The numbers in the following table are needed to identify the taper of a potentiometer. Unfortunately, similar-sounding letters are used in different standards, leading to potential confusion. Measuring the taper twice is an intelligent safety measure.

● Resolution

A potentiometer’s resolution is the smallest ratio of resistance to which it can respond. The resolution of wirewound resistors is typically lower than that of film or film-coated varieties because the wire turns to introduce discrete increments in resistance. Most accurate potentiometers are made of conductive plastic. Wiper design can affect resolution; a wiper with widely spaced contact points allows for finer adjustments to the potentiometer.

● Hop-on and Hop-off resistance

A potentiometer’s resistive track is connected to the end terminals through low-resistance metal pieces at both the beginning and end of the adjustment range. The hop-on and hop-off resistance refer to the difference in opposition when the wiper enters and leaves the resistive track.

● Applications for Pots

Potentiometers have various uses and can be found in many different businesses. There are so many other applications that it would be difficult to list them all here. It is possible to use it as a control input, a component for position measurement or calibration, and a great deal more.

● User controlled inputs

Potentiometers are frequently utilized in situations where the operator of a machine or application is required to provide changeable input. Automotive throttle pedals are usually dual-gang potentiometers. This is done to maximize the system’s level of redundancy. Joysticks are another application of pots that are used for controlling machines.

● Audio control

In audio applications, the volume is typically adjusted using a potentiometer, which can be either manual or motorized. Potentiometers with two separate gangs can be used for balance control. One gang of the potentiometer should have a logarithmic taper, and the other should have an inverse logarithmic taper. Faders are standard pieces of hardware found in professional audio equipment.

● Position or angle transducer

When measuring distances or angles, potentiometers are frequently employed as position or angle transducers.

● Calibration and tuning

Trimpots are frequently utilized in the processes of manufacture and calibration. Trimpots are a type of preset potentiometer that can be used to tune or change the performance of an electronic circuit. These potentiometers are often located on a circuit board. They are only utilized when the system is calibrated and spend most of their time in a stationary state. A little screwdriver with a flat head is typically used to adjust trim pots. There are a few other names for trumpets, including presets, trimmers, and trimming potentiometers.
