Variable Resistor

Product Specifications & Features

• Adjustable Resistance Range: Designed to provide a wide range of resistance values (e.g., 1kΩ, 10kΩ, 100kΩ), allowing for precise control over voltage and current in a circuit.
• Taper Types: Available in two primary adjustment curves:
  • Linear (Type A): Resistance changes at a constant rate (ideal for voltage dividers).
  • Logarithmic (Type B/Audio): Resistance changes exponentially (standard for volume controls).
• Standard Sizes & Mounting:
  • Potentiometers: Standard 6mm or 1/4″ shaft diameters for panel mounting.
  • Trimmer Resistors (Trimpots): Miniature footprints (e.g., 6mm or 9mm squares) for through-hole or SMD board mounting.
• Power Ratings (Wattage): Built to handle varying power loads depending on size:
  • Miniature Trimpots: Typically 0.1W to 0.25W.
  • Standard Panel Pots: Typically 0.25W to 0.5W.
  • Wire wound Power Pots: Can handle 1W to 5W+ for heavy-duty applications.
