10K 3386P Trimpot (Pack of 5)

Description

The 10K 3386P Trimpot is a precision trimmer potentiometer designed for precision circuit adjustments in various electronic applications. This component is a variable resistor that allows for precise adjustment of resistance values within a specific range. This pack includes five (5) individual trim pots, ideal for prototyping, development, and production purposes.

Functionality

The 10K 3386P Trimpot serves as a variable resistor, enabling the user to adjust the resistance value between the input and output terminals. The trimmer potentiometer has three terminals

one for the input signal, one for the output signal, and one for the wiper (adjustment terminal). The wiper terminal is used to adjust the resistance value by rotating the trimmer's adjustment knob. This adjustment changes the proportion of the input signal that is sent to the output terminal, allowing for precise control over the signal amplitude.

Pin Configuration

Component Documentation: 10K 3386P Trimpot (Pack of 5)
Pinout Diagram:
The 10K 3386P Trimpot is a 3-terminal potentiometer, with three pins: CW (Clockwise), CCW (Counter-Clockwise), and W (Wiper). Below is a detailed explanation of each pin:
Pin 1: CW (Clockwise)
Function: Connects to the highest potential (voltage) in the circuit.
Description: The CW pin is the terminal that connects to the voltage source or the positive leg of the circuit.
Connection: Typically connected to VCC (power supply voltage) or a voltage divider network.
Pin 2: W (Wiper)
Function: Output terminal that varies with the potentiometer's rotation.
Description: The Wiper pin is the output terminal that changes its voltage level as the potentiometer is rotated.
Connection: Typically connected to the input of a circuit or a device that requires a variable voltage or resistance.
Pin 3: CCW (Counter-Clockwise)
Function: Connects to the lowest potential (voltage) in the circuit.
Description: The CCW pin is the terminal that connects to ground or the negative leg of the circuit.
Connection: Typically connected to GND (ground) or a voltage divider network.
Connection Structure:
Here's a general connection structure for the 10K 3386P Trimpot:
Pin 1 (CW): Connect to VCC (power supply voltage) or a voltage divider network.
Pin 2 (W): Connect to the input of a circuit or a device that requires a variable voltage or resistance.
Pin 3 (CCW): Connect to GND (ground) or a voltage divider network.
Example Circuit:
A basic example of using the 10K 3386P Trimpot as a voltage divider is shown below:
Pin 1 (CW): Connect to VCC (e.g., 5V).
Pin 2 (W): Connect to the input of a microcontroller's analog-to-digital converter (ADC) or a variable resistor network.
Pin 3 (CCW): Connect to GND.
By rotating the potentiometer, the voltage at the Wiper pin (Pin 2) will vary between 0V and 5V, allowing for a range of voltage outputs.
Important Notes:
When using the trimpot as a variable resistor, ensure that the current flowing through the potentiometer does not exceed its maximum rating.
The 10K 3386P Trimpot has a maximum power rating of 0.5W, so make sure to stay within this limit to avoid damaging the component.
I hope this documentation provides a clear understanding of the 10K 3386P Trimpot's pinout and connection structure!
