A trimmer potentiometer is an electro-mechanical device designed to adjust, tune, and calibrate circuits and function as a voltage divider or rheostat. Trimmer resistors are usually cermet or carbon composite and can be connected directly to printed circuit boards (PCBs). They are typically used for the initial calibration of equipment after manufacturing.
Also, the potentiometers do not adjust frequently and follow the "set and forget" properties. These adjusting pots allow you to tune resistors to achieve precise currents, output voltages, or gain. Once the value is set, it is unlikely that the trimmer needs to be restarted unless the circuit needs to be reset.
Other Names for Trimmer Potentiometer
They are also called trim pots, trimmer resistors, preset potentiometers, and adjustable potentiometers.
What are the Applications of Trim Pot?
- Used to calibrate and fine-tune circuits.
- Voltage and current control circuits.
- Used as a volume control button on the radio and the bias current on power amplifiers.
- Circuit change or check the circuit.
- Analog input control button.
- They exhibit a "set and forget" application that "cuts" the resistor values and provides the correct gain, output voltage, or current.
- Mainly in precision circuits such as A/V components, calibration instruments, and setups.
What Benefits Do Our Products Offer?
Key benefits of our trimmers include:
- Lower temperature.
- Higher power dissipation.
- Lower noise.
- Tighter operating pressure.
- The ability to carry good current due to lower contact when used to make a difference.
- In addition, our products also offer better working time stability over time and temperature.
Is There Any Difference Between Standard and Trim Pots?
Trim pots are extremely durable and possess unmatched features compared to the standard ones. Trimmer pots are generally more expensive than standard potentiometers with a more stable measurement but have a different lifespan. Many potentiometers have a long life that allows hundreds of thousands of cycles. Trim pots are the best and typically have a long life of several hundred cycles. Also, trim pots take up more space on the PCB than standard pots.
Need a Single-turn or Multi-turn Trim Pot?
It all depends on the intended use of the trim pot. Multi-turn potentiometers will have a higher resolution than standard single-turn models. Single-turn trimmers are ideal for use where a single solution is sufficient.
Why Choose Our Product?
Enrgtech provides elegant and durable potentiometers that are easily adjustable by hand. Simply twist the knob with your finger. They can also be easily adjusted using screws or special adjustment tools designed for use with special designs, models, or series.
How to Use a Trim Pot?
To use the trim pot, connect the CCW and CW terminals to the input and ground terminals, respectively, and get the output voltage difference from the wiper terminals. Turn the screw on the trim port to change the output voltage. This screw turns a wiper located in the port to change the resistance.
