  • 15 mm shaft length allows easy knob attachment
  • Two pieces included for stereo or dual-channel builds

B100K Linear Slide Potentiometer

The Unique-Bargains B100K is a passive linear slide potentiometer supplied as a pack of two units. It provides a single-channel variable resistance path for manual control of voltage or current in audio and lighting circuits. The component suits hobbyists, repair technicians and builders of small mixing consoles or instrument preamps who need straightforward level adjustment.

100K ohm resistance with ±10% tolerance

The defining electrical parameter is the 100K ohm nominal resistance with a tolerance of ±10 percent. This value determines the load presented to the driving stage and the attenuation range available. Selecting this part requires matching the circuit design to that specific impedance and tolerance window.

Linear resistance change through 45 mm travel

The resistive element varies linearly along the 45 mm shaft travel, giving a predictable relationship between slider position and output level. The 15 mm shaft length and three-terminal construction allow panel mounting and standard wiring. Under continuous adjustment the carbon track maintains consistent linearity without the sudden jumps found in logarithmic types.

Questions about this item

What does the 100K ohm resistance mean for a volume fader in a mixer?

It sets the signal impedance so the audio taper feels even from silence to full level across the 45 mm travel.

How does the single-channel, three-terminal layout limit what I can control?

One fader adjusts one circuit only — volume, tone or balance — so stereo needs two units.

Will the 15 by 4 mm shaft fit the knob and panel cut-out I already have?

The shaft is 15 mm long and 4 mm wide; the body measures 45 by 9 mm, so verify your knob bore and panel hole against those dimensions.
