Trimmer Potentiometers

A trimmer potentiometer, also known as a trim pot, is a small adjustable potentiometer which is used for calibration in electronic circuits. They typically feature three terminals used to adjust resistance, and are used when a precise level of adjustment is required. The PV36Y203A01B00 trim pot is a particular type of potentiometer which is commonly used in circuitry.

Application Field

PV36Y203A01B00 trimmer potentiometers are primarily used in audio circuitry, particularly in the tuning and alignment of audio systems such as radios, speakers and amplifiers. For example, they can be used to adjust the gain of an amplifier to suit the audio signal. Additionally, they are used for adjustment and calibration purposes in electronic circuits, such as to set the level of current in a circuit.

Working Principle

PV36Y203A01B00 trimmer potentiometers are constructed from three terminals: a wiper, a fixed end and a variable end. The fixed end is a connection to a fixed resistor which does not change in resistance, and the variable end is a connection to a sliding resistor which is adjustable. The wiper terminal is connected to a rotatable contact which slides along the variable end, creating a variable resistor which can be adjusted through the rotation of the contact. The resistance of the potentiometer is equal to the sliding resistor plus a small amount of fixed resistor, and it can be adjusted from a minimum to a maximum resistance depending on the range of the product. The purpose of this construction is to allow fine tuning of a circuit by altering the resistance across a component.

In addition to the physical construction of the trim pot, the working principle also involves two other important concepts: linearity and tolerances. Linearity indicates the relationship between the resistance of the variable resistor and the angle of rotation of the contact, whereas the tolerance is the maximum allowable difference between the stated resistance and the actual resistance.

Overall, the PV36Y203A01B00 trimmer potentiometer is a small adjustable potentiometer which is used for calibration and fine adjustment of electronic circuits. It is constructed from three terminals which are used to adjust resistance, and is commonly used in audio circuitry. It features principles of linearity and tolerances, allowing precise adjustment and tuning of circuits.
