Trimmer Potentiometers: 84PR500KLFTR Application Field and Working Principle

Trimmer potentiometers are electronic components widely used in many applications in industrial, automotive and consumer electronics industries. The 84PR500KLFTR series is just one of them, a high-performance trimmer from precision resistive components manufacturer TT Electronics. It offers precision tuning and reliability, as well as resistance options ranging from 4kΩ up to 10MΩ.

What is a Trimmer Potentiometer?

A trimmer potentiometer is an adjustable electrical resistor, usually with three terminals. It consists of a resistive element, usually in the form of a carbon track, or metal film or wirewound coil, and a sliding or rotating actuator. It allows you to fine-tune the resistance from the minimum to the maximum available.Trimmer potentiometers are primarily used to adjust the gain of audio amplifiers or to control the brightness or contrast of a display. They are also used to set the timing of an oscillator or adjust the sensitivity of sensors in a wide range of applications.

84PR500KLFTR Application Field

The 84PR500KLFTR trimmer series are designed primarily for audio tuning and calibration applications. They have a wide adjustment range, with resistance values from 4 kΩ to 10 MΩ. The series is also designed to handle power up to 5W. It is resistant to shock and vibration, and offers fast settling times, making it suitable for consumer and industrial electronics.In terms of performance, the 84PR500KLFTR series offers excellent stability and high accuracy tolerance (±0.25%). It also has a low temperature coefficient of resistance (TCR) of ±200ppm/°C.In terms of physical dimensions, the series measures 18.0 x 13.0 x 7.7mm; and is conformally coated, which increases its durability under environmental and workplace conditions.

84PR500KLFTR Working Principle

The 84PR500KLFTR series of trimmer potentiometers have a three-terminal construction, with a resistive element acting as a voltage divider. The two outer terminals are connected to the ends of the resistive element, while the middle terminal is connected to the actuator.When the actuator is moved from the far right to the far left, the resistor’s resistance is decreased and the output voltage is increased. When the actuator is moved from the far right to the far left, the resistor’s resistance is increased and the output voltage is decreased.The 84PR500KLFTR trimmer series has a wide resistance range and excellent frequency response. It can be adjusted with a wide variety of voltage levels (from 0.1V to 28V) and its temperature coefficient is controlled by an external resistor.

Conclusion

The TT Electronics 84PR500KLFTR trimmer series is designed for precision tuning applications. It provides a resistance range from 4 kΩ to 10 MΩ and is capable of handling up to 5W of power. It is resistant to shock and vibration, has a low temperature coefficient of resistance, and features an excellent frequency response. Its high accuracy tolerance and superb stability make it suitable for many high-end industrial, automotive, and consumer electronics applications.
