Trimmer Potentiometers

Trimmer Potentiometers are small adjustment components used in electronic circuits to adjust the electrical potential of a system. Common applications include volume control, frequency tuning, and current limiting. The T18202KT10 is a trimmer potentiometer, manufactured by Seikai, which has an operational range of 6V – 24V. It has a circular shape and is about 1.3 inches in diameter and 0.5 inches thick.

Application Field

The T18202KT10 is ideal for applications where space is limited, such as cell phones, tablets, and other mobile devices. It is also suitable for robotic control systems, measuring and testing instruments, and appliances. This trimmer potentiometer can be used as a replacement for traditional potentiometers in any application which requires linear adjustment of electrical potential.

Working Principle

The T18202KT10 is equipped with three terminals to which a voltage is applied. These terminals are typically connected to the three leads of a power supply. The voltage across the terminals can be adjusted using the gear knob attached to the rear of the device. This knob rotates a central mechanism which disperses the voltage across the three terminals, creating a potential between them.

When the position of the knob adjusts the voltage across the two outer terminals, the third terminal will have a different potential than the other two. By monitoring the change in potential at that terminal, it is possible to measure the position of the knob and control the amount of current flowing in the circuit. This allows the system to be precisely adjusted for the desired level of electrical potential.

Conclusion

The T18202KT10 trimmer potentiometer is a compact and simple way to precisely adjust electrical potential in a variety of applications. Its low profile and robust construction make it an ideal choice for a variety of situations. With its three terminal connection and rotating knob actuator, it is able to accurately control the voltage between its terminals, giving it great flexibility.
