The 10k Ohm Linear Variable Potentiometer is the industry-standard component for providing adjustable control in electronic circuits. At Electrapac, we supply high-quality, durable potentiometers designed for both breadboard prototyping and permanent panel mounting.

Product Overview

This 10k Ohm potentiometer (often labeled as B10K) acts as a variable voltage divider. As you rotate the shaft, the internal wiper moves across a resistive element, allowing you to manually adjust voltage, current, or signal levels. Whether you are controlling the volume of an amplifier or the brightness of an LED, this "Good Quality" variant ensures smooth rotation without the "crackling" or dead spots found in lower-grade alternatives.

Key Features for Electrapac Customers

• Smooth Linear Response: Unlike logarithmic pots, this linear version provides a consistent change in resistance relative to the angle of the knob, making calibration predictable.

• Panel-Mount Ready: Comes with a matching nut and washer, allowing you to secure it firmly to plastic project boxes or aluminum faceplates.

• Solder-Lugs or Breadboard Use: The three sturdy metal terminals are designed to accept hook-up wire for soldering or can be slightly adjusted to fit into a standard breadboard.

• Long Rotational Life: Tested for thousands of cycles to ensure the internal carbon track remains intact even with frequent use.

• Standard 6mm Shaft: Compatible with almost all standard push-on or screw-set plastic and aluminum knobs available at www.electrapac.com.

Pinout & Connection Guide

For a standard voltage divider setup (like an Arduino Analog Input):

1. Pin 1 (Left): Connect to Ground (GND).

2. Pin 2 (Center/Wiper): Connect to your Analog Pin (e.g., Arduino A0). This provides a signal between 0V and 5V.

3. Pin 3 (Right): Connect to VCC (e.g., 5V).

Primary Applications

• Arduino/Microcontroller Inputs: Providing a manual user-adjustable value for software parameters.

• Audio Equipment: Controlling volume, tone, or gain in DIY speakers and amplifiers.

• Motor Speed Control: Acting as the input for PWM-based DC motor speed controllers.

• Lighting Dimmer: Adjusting the brightness of LED strips (when used with a driver).

• Power Supplies: Fine-tuning the output voltage of adjustable DC-DC converters.

Why Shop at Electrapac?

We source our 10k Potentiometers with reinforced internal contacts to prevent signal jitter. At www.electrapac.com, we provide the tactile components that bridge the gap between human input and electronic execution.
