Trimmer Potentiometers

A Trimmer Potentiometer, commonly known as a trimmer pot, trim pot, trimpot or trimmer, is a variable resistor which is used for setting and adjusting the electrical parameters of a circuit. Trimmer Potentiometers are most commonly used in applications where sensitivity and accuracy are important, such as in radio frequency and audio circuits. This article will provide an overview of the ST2 TA 202 trimmer pot and its application field and working principle.

ST2 TA 202 Trimmer Potentiometers

The ST2 TA 202 is a trimmer potentiometer designed and manufactured by STMicroelectronics, a leader in the development and production of advanced semiconductor solutions. This trimmer pot is constructed with a cermet element and is available with a range of values from 10k to 1M ohms and a maximum power rating of 0.1W. Its small size and robust design make it ideal for applications with space constraints. ST2 TA 202 trimmer pots feature full range linearity and low temperature coefficient for superior performance.

Application Field and Working Principle of the ST2 TA 202

The ST2 TA 202 is used in a variety of applications in which sensitivity and accuracy are required, including in radio frequency and audio circuits. It is also widely used in industrial electronics, home electronics, medical equipment, instrumentation, automotive electronics and consumer electronics such as mobile phones and tablets. The trimmer pot works by adjusting the position of a contact on its’ element, thereby changing the resistance of the circuit. By adjusting the position of the contact, the resistance of the circuit can be varied to a desired value.

The ST2 TA 202 is a three terminal device, with a control pin, a ground pin and a power pin. When the control pin voltage is adjusted, the surface stripe position of the trimmer potentiometer can be changed and the resistance value can be modified. The control pin can be adjusted with the help of a screwdriver, which is inserted into the top of the trimmer pot. The resistance value can be read from the scale on the surface of the trimmer pot. The ST2 TA 202 is available with a selectable turn ratio (1, 5, 10, 15 and 20). The turn ratio is the number of turns of the knob of the trimmer pot needed to move the contact from one end to the other, and is determined by the resistance range of the trimmer pot.

The ST2 TA 202 trimmer pot offers superior performance and reliability, and is available in a variety of package options such as SMD, DO-41, through-hole, and others. This trimmer pot is also RoHS compliant, making it suitable for a wide range of commercial, industrial and home electronics applications.

In conclusion, the ST2 TA 202 trimmer pot is an ideal choice for applications where sensitivity and accuracy are important, such as radio frequency and audio circuits. Its small size, robust design and various package options make it suitable for a wide range of applications. It is also RoHS compliant and offers superior performance and reliability.
