Trimmer Potentiometers are devices that allow for fine-tuning of resistance values in controlled circuits or systems. They are composed of three pins and a sliding arm that is connected to a slider – the slider is responsible for adjusting the resistance between the two outer pins. The 3318G-1-202A Trimmer Potentiometer, produced by Bourns Inc., is a versatile and reliable model that has a number of applications in industries spanning from consumer electronics to automotive applications.

Applications

The 3318G-1-202A is capable of providing accurate and uniform resistances for quick and repeatable adjustments in a variety of applications. The device has the flexibility to be used in single-turn or multi-turn settings, giving it a wide range of applications across various fields. In the consumer electronics industry, the 3318G-1-202A is used to adjust audio equipment, such as volume controls, balance controls, and tone controls. The device also finds uses in the automotive industry, as it is capable of providing accurate and repeatable adjustments to engine control systems and fuel injection systems. The 3318G-1-202A has also been employed in medical equipment, altitude guidance systems, and communications systems.

Features

The 3318G-1-202A has a number of features that make it an ideal trimmer potentiometer for wide range of applications. It has an adjustable resistance range of 5kΩ to 10kΩ, with a rotational life of 1,000-2,000 cycles. The device is protected against dust and moisture to a certain degree, and is made with a polyester substrate to ensure stability of the electrical characteristics. The 3318G-1-202A also works with a wide range of operating temperatures from -55°C to +105°C, and it has a good thermal-shock resistance that allows it to maintain stable performance in temperature cycling tests.

Working Principle

The 3318G-1-202A works on a basic principle of variable resistor. The device is composed of three pins, two of which are connected by a resistor and the third one forms the sliding arm. As the sliding arm is moved from one extreme to the other, the resistance values between the outer pins change accordingly. By moving the sliding arm, different resistance values can be achieved, allowing the device to be used in a number of applications.

Conclusion

The 3318G-1-202A Trimmer Potentiometer from Bourns Inc. is a versatile and reliable device that provides accurate and repeatable adjustments for a wide range of applications. Its features, including adjustable resistance range, dust and moisture protection, wide range of operating temperatures, and good thermal-shock resistance make it the perfect choice for a number of industries. The device works on the same principle of a variable resistor, which provides resistance values by moving the sliding arm from one extreme to the other. With so many great features, the 3318G-1-202A is an excellent choice for reliable and accurate adjustment solutions.
