3306W-1-204

Trimmer Potentiometers are electrical components used to precisely adjust the electrical resistance value in circuits, and the 3306W-1-204 model is one type of trimmer potentiometer. It consists of a resistive element usually made of cermet, ceramic, or a film element, with two end terminals connected to the element and a third terminal connected to a sliding contact, known as the wiper, which moves on the resistive element. The length of the element and terminal spacing of this model is 3.0 mm. Its electrical rating is 1 watt at 70 ℃

The major application fields for the 3306W-1-204 trimmer potentiometer are diverse, and the most common ones are in volume, tone, or balance control circuits in audio equipment, as well as for adjusting the contrast/brightness, horizontal/vertical size/position, and color in TV sets. It is also seen a lot in precision, high-volume production applications in the automobile and aviation industries.

The working principle of a trimmer potentiometer is relatively simple. When the external voltage is applied to the two terminals on the resistor’s ends, current flows through the resistor. When the contact on the trimmer potentiometer (the wiper) is moved along the resistor’s element, the voltage applied to the wiper changes, and this changes the current’s value accordingly. This type of trimmer potentiometer is especially useful when precise adjustments are needed in order to fine tune circuits accurately.

Overall, the 3306W-1-204 trimmer potentiometer provides a great way to precisely adjust the resistance value in various types of circuits. Its wide range of applications make it suitable for both consumer and commercial use, and its working principle allows for accurate, fine tuning of circuits.
