Trimmer potentiometers, such as the 3386C-1-200, are devices used to adjust the resistance level of various circuits. The 3386C-1-200 features a small footprint, and is commonly used in military, aerospace, medical, and automotive applications. They are also commonly used to tune and adjust the performance of audio and radio equipment. Here, we will take a look at the 3386C-1-200\'s application field and working principle.

Application Field

The 3386C-1-200 is a three-terminal multiturn cermet trimmer potentiometer with couplant and terminal seal. Its resistance range is 250Ω to 500kΩ. It is designed to be used in applications requiring a wide resistance range and low inductance values. It can also be used in high-voltage, DC-DC converters, motor drives, and other power supplies. The 3386C-1-200 is rated for up to 10W of power dissipation.

It has high reliability, with a long-term stability of 0.3% (maximum) over a 50,000-hour period. The 3386C-1-200 is also designed to meet the requirements of military and aerospace applications, as it is qualified according to Mil-PRF-55342 and is available in a variety of case sizes and terminal configurations. The 3386C-1-200 is also RoHS Compliant, and is designed to be resistant to shock and vibration. The terminal seal ensures hermetic protection, making the 3386C-1-200 suitable for use in extreme environments.

Working Principle

The 3386C-1-200 is a multiturn trimmer potentiometer, which means that it has multiple resistance positions. This is achieved by having two sliding contacts located on a resistance track. As the contact is rotated, the resistance between the contacts increases or decreases, depending on the direction of rotation. As the contact moves, the resistance track changes its shape, which produces different resistances at different points along the track.

The 3386C-1-200 uses a helical resistance track, which allows it to achieve a high level of resolution and accuracy. This makes it suitable for use in precision applications. The 3386C-1-200 also has a locking mechanism, which prevents it from being unintentionally adjusted. This is especially important in military and aerospace equipment, where reliability and accuracy are paramount.

The 3386C-1-200 trimmer potentiometer is a versatile device that can be used in a wide range of applications. Its small footprint and long-term stability make it a suitable choice for use in military, aerospace, medical, and automotive applications. Its resistance range and precision make it suitable for tuning and adjusting audio and radio equipment. With its hermetic terminal seal, the 3386C-1-200 is even suitable for use in extreme environments.
