Trimmer Potentiometers

The 3386C-1-203 is a Trimmer Potentiometer, which is a type of variable resistor that has a single rotating contact that functions as a wiper. This type of Potentiometer is used to control the tilt of antennae mounted on satellites, and it is employed for many other precision resistive applications. The following is a look at its application field and working principle.

The primary application of the 3386C-1-203 is in precision resistive applications, with the common examples being where it is used to fine-tune a circuit or to get the most precise level of output current possible. This type of Potentiometer is precise and stable, and most versions offer a rotation of up to 270 degrees which allows for an even distribution of resistance around the turning axis.

These Potentiometers are also used in mission-critical applications where absolute resistive control is a must. Examples of its use in this type of operation include heaters, optical systems, motion control, and even motor speed control. Within these high-end applications, they often require additional functionality such as temperature compensation, which is where the Trimmer Potentiometer stands out as a reliable solution.

In terms of its working principle, the 3386C-1-203 is based on the voltage divider principle. It works by having a fixed resistor at one end of an electrical path and then having a moving contact, called the wiper, that moves along the path and changes the resistance between the two ends over time. The output voltage is determined by the resistance between the two ends and the wiper position. In this type of Potentiometer, the wiper is adjusted using a screwdriver or knob to achieve variable resistances between the two ends.

The 3386C-1-203 is unique when compared to other Potentiometers because of its shock-resistant design, which is ideal for use in hostile environments or in applications that require high accuracy. This technological feature makes it a great choice for applications like temperature compensation because of its consistent performance over a wide range of temperatures. Additionally, the Potentiometer features a soft-grip handle, so it can be adjusted with accuracy and ease.

Overall, the 3386C-1-203 is a fantastic Trimmer Potentiometer solution that is designed for use in precision resistive applications. It is shock-resistant and features a soft-grip handle for better control, which makes it great for controlling the tilt of antennae mounted on satellites and for many other mission-critical uses. It works by using the voltage divider principle with a fixed resistor at one end of the electrical path, with a moving contact, called the wiper, that moves along the path and changes the resistance between the two ends.
