Introduction of Trimmer Potentiometers

Trimmer Potentiometers are small precision variable resistors which are used for adjusting and controlling the circuit parameters in electronic, radio, telecommunications, computers, calculators and other products. It is generally used for simple adjustment of two-terminal devices, such as those that are used in volume and tone control circuits. The most common type of trimmer potentiometer is the 68XR100KLFTB. This device is based on the principle of a two terminal resistor where the position of the wiper along the resistance element is used to vary the resistance between the two terminals. The 68XR100KLFTB is a potentiometer with three leads, two of which are dedicated to the resistance element and the third is used to adjust the wiper position along the resistance element. This type of trimmer is highly accurate and is used for fine adjustments.

Application Field of 68XR100KLFTB

The 68XR100KLFTB trimmer potentiometer is used in a wide variety of applications. It is used in audio products such as pre-amplifiers, audio mixers, equalizers, and amplifier circuits. It is used in radio devices such as radio receivers and amplifiers as well as in motor speed controllers and turn-by-turn navigation systems. It is also used in precision temperature controllers, controllers of solar cell charge systems, and in voltage regulators.

Working Principle of 68XR100KLFTB

The 68XR100KLFTB trimmer potentiometer has three terminals. Two of these terminals are dedicated to the resistance element and the third is used to adjust the wiper position along the resistance element. When the wiper is set at the end of the resistance element, the resistance is equal to the resistor value. As the wiper is adjusted along the resistance element, the resistance between the two terminals varies accordingly. The adjustment of the wiper can be done manually or electronically. When the trimmer is adjusted manually, it is important to ensure that it is not over-adjusted as this can damage the device. When adjusting the trimmer electronically, the position of the wiper can be changed by applying voltage or current to the third terminal.

Conclusion

The 68XR100KLFTB is a trimmer potentiometer which is used for adjusting and controlling circuit parameters in electronic and radio products. It works on the principle of varying the resistance between two terminals by adjusting the wiper along the resistance element. The 68XR100KLFTB is used in audio and radio products as well as in motor speed controllers, temperature controllers, solar cell charge systems and voltage regulators. It can be adjusted manually or electronically.
