Trimmer Potentiometers

The PV36P502C01B00 trimmer potentiometer is a three-terminal adjustable electrical device that can be used in a wide variety of applications.

The device\'s two end terminals are connected internally, with a center tapping point allowing for adjustable current passing through the device. It is a type of variable resistor which is installed as a component of a circuit and when it’s adjusted, the circuit behaves according to the adjustment. The following applications are suitable for the use of the PV36P502C01B00.

Application Field

The trimmer potentiometer is often found in sensitivity adjustment, meaning the level of input can be fine-tuned. Usually, this occurs in radio receivers and transmitters, where it is important to adjust the signal levels. In audio amplifiers and mixers, this device is used for volume and tone control. Trimmer potentiometers can also be used for the calibration of electronic instrumentation systems and medical equipment.

Often, the taps can be moved electrically or mechanically, with the addition of a resistance element, depending on the application at hand. Some circuit boards provide slots that are designed specifically for trimmer potentiometers, allowing for faster and easier installation and upgrade of components.

Working Principle

The PV36P502C01B00 is a component that adjusts the voltage or current of a circuit on command. It functions by working with a circuit to either decrease the voltage, increase the current, or develop an offset. It is an important part of regulated power supplies.

The epoxy-sealed case of the PV36P502C01B00 contains a resistive track that can be adjusted using a tool. This is usually done with a tiny screw-like device known as a wiper that performs the adjustment. When the wiper is moved around the track, it adjusts the resistance in the track. As the resistance is changed, the current in the circuit will be correspondingly adjusted accordingly.

The PV36P502C01B00 comes in two linear forms: single turn and multi-turn. Single turn trimmer potentiometers are most often used for small adjustments, as they usually can only turn one full turn. Meanwhile, multi-turn trimmer potentiometers are used for more precise adjustments with up to 20 full turns.

As a precision instrument, a trimmer potentiometer is often used in systems where accuracy and repeatability are crucial, such as in telecommunications systems and medical equipment. The manufacturers of these devices often acknowledge their performance instability. An upgrade may be necessary for precision applications after a certain amount of time, depending on the environment that the device is operating in.
