12-piece 100K ohm carbon film potentiometer kit

This kit contains twelve single-turn carbon film potentiometers rated at 100K ohm with a ±20% tolerance. Each unit features a 6 mm round shaft, 14 mm shaft length, and a 6.7 mm screw thread diameter for panel mounting. The package includes twelve matching plastic knobs measuring 17 by 15.7 mm for immediate use.

Linear resistance adjustment for audio

The carbon film element provides a linear taper suitable for volume controls on audio equipment and general variable resistance tasks. Single-turn operation allows full range adjustment in one rotation, while the knurled split shaft secures the supplied push-on knobs without tools. Horizontal mounting orientation suits breadboard and PCB prototyping.

Verify shaft dimensions

Confirm that the 6 mm shaft diameter and 14 mm shaft length fit your panel cut-out and knob clearance requirements. The ±20% resistance tolerance means actual values may vary significantly from the nominal 100K ohm rating. Ensure the three-terminal pin spacing matches your board layout and that single-turn resolution meets your precision needs.

Questions about this item

Does the 100K ohm carbon film element generate noticeable heat when adjusted continuously during a long session?

The potentiometer is a passive 100K ohm carbon film device rated for low signal-level adjustment; it does not dissipate significant power and produces no perceptible heat during normal knob rotation.

What shaft dimensions must my panel or breadboard accommodate for the 6.7 mm threaded bushing and 14 mm shaft length?

Each unit has a 6.7 mm screw thread diameter, a 6 mm smooth shaft diameter and a 14 mm shaft length below the thread, so the mounting hole and panel thickness must match those figures.

Will the included 17 x 15.7 mm plastic knobs fit the 6 mm knurled split shafts on older potentiometers I already own?

The knobs are moulded for the 6 mm split shaft on these WH148 units; they will only fit other potentiometers that share the same 6 mm knurled split-shaft profile.
