Trimmer Potentiometers, abbreviated as TP, are variable resistors with 3 pins. TP are often used as adjustable elements for electronic circuits, and are mainly available in two types of Multi-Turn and Single-Turn. TP are mainly used to adjust an electrical parameter such as resistance, gain, frequency, current or voltage. One of the most commonly used TP is the 84WR200KLF. This article will discuss the application fields and working principle of the 84WR200KLF Trimmer Potentiometer.

Application Fields

The 84WR200KLF has a wide range of application in electronic circuits. For example, it can be used for linear and logarithmic adjustments, band-pass filters, DC gain adjustments, and voltage regulation.

• Linear and Logarithmic Adjustments - The 84WR200KLF can be used to adjust the impedance of electronic circuits, providing an adjustable signal level. It can also be used to adjust the sensitivity of the circuit to input signals.
• Band-Pass Filters - The 84WR200KLF can be used to pass a certain frequency range, allowing signals with a specific range to pass while filtering out other ones. It can be used to filter out unwanted signals from entering a circuit.
• DC Gain Adjustments - The 84WR200KLF can be used to adjust the DC gain of a circuit. It is most often used to adjust the gain of an operational amplifier.
• Voltage Regulation - The 84WR200KLF can be used to regulate voltages. This can be used in circuits such as power sources, voltage regulators or amplifiers.

Working Principle

The 84WR200KLF is a 3-terminal device, with the third terminal connected to a wiper that moves across a resistor when the shaft is turned. As the wiper moves, the resistance between the output terminal and the wiper varies, thus regulating the voltage or current in the circuit.

The resistor is usually made up of carbon or metal strips formed on a substrate. Other materials such as ceramics can also be used to construct the resistor. The substrate is usually an insulator, preventing the wiper from shorting out the resistor.

The 84WR200KLF has a wide variety of adjustable parameters such as resistance, gain, frequency, current or voltage, depending on the application.

Conclusion

In conclusion, the 84WR200KLF is a versatile and widely used Trimmer Potentiometer. It has a wide range of applications in circuits and can be used to adjust various parameters such as resistance, gain, frequency, current or voltage. Its working principle is based on the use of a resistor and a wiper, which can be adjusted manually or automatically to regulate the voltage or current in the circuit.
