Product Description: The 100K Ohm Logarithmic Taper Potentiometer from Elcon is a high-quality rotary component specifically designed for audio applications. Unlike linear potentiometers, the logarithmic taper matches the human ear's non-linear perception of sound, providing a smooth and natural volume adjustment. Its compact 16mm body makes it ideal for guitar pedals, amplifiers, and custom audio interfaces.

Key Features

  • Audio-Optimised Taper: Provides a smooth volume curve that feels natural to the listener.

  • Precision Splined Shaft: The 18-tooth knurled shaft ensures a tight, slip-free fit for standard push-on knobs.

  • Compact 16mm Profile: Saves valuable space inside enclosures and on high-density PCBs.

  • Durable Metal Shaft: Engineered to withstand frequent manual rotation without mechanical fatigue.

  • Low Noise Operation: High-quality carbon element reduces "crackling" sounds during adjustment.

Technical Details

  • Logarithmic Logic: In a Type A pot, the resistance increases slowly at first and more rapidly toward the end of the turn to compensate for logarithmic hearing.

  • Mounting Depth: Designed with a standard threaded neck for secure panel mounting through various materials.

  • Operating Temperature: Rated to perform reliably under standard electronic operating conditions.

Prototyping and Engineering Tips from Robogears

  • Powering with a 9V Battery: This 100K pot is perfect for 9V battery-powered pre-amps. Since it has high resistance, it draws very little current, preserving battery life.

  • Capacitor Pairing: Pair this with a 0.1uF or 0.047uF ceramic capacitor to create a "Tone Control" circuit for guitars or audio filters.

  • Standard Resistor Use: If using this as a variable gain control for an LM386 IC, ensure your input signal is grounded through the third pin to prevent floating noise.

  • Related Products: Works seamlessly with our PAM8403 amplifier modules or TDA series audio ICs.

Package Includes
