20K 3386P Trimpot (Pack of 5)
The 20K 3386P Trimpot is a type of precision potentiometer designed for adjusting electrical resistance in a wide range of electronic circuits. This component is part of the trimmer potentiometer family and is commonly used in applications requiring precise resistance adjustments.
The primary function of the 20K 3386P Trimpot is to divider a voltage signal and provide a variable output voltage that is proportional to the position of the potentiometer's mechanical shaft. The component features a three-terminal configuration, with one terminal connected to the input voltage, one terminal connected to the output voltage, and the third terminal connected to the circuit ground.
| When the shaft is rotated, the resistance between the input and output terminals changes, allowing the user to adjust the output voltage to a specific level. This functionality makes the 20K 3386P Trimpot an essential component in various applications, including |
Voltage dividers
Signal attenuators
Gain control circuits
Audio equipment
Industrial control systems
