20K Ohm Potentiometer Pack

The Unique-Bargains B203 is a set of five horizontal multiturn trimmer potentiometers. Each unit provides a 20K ohm resistance value with a +/-10% tolerance. They are designed for dial adjustment with linear resistance change. The compact 16 x 6mm size suits breadboard prototyping and audio volume control circuits.

Linear Adjustment Constraints

The wheel dial provides linear resistance variation across its rotation range. The +/-10% tolerance means the actual resistance can deviate from the nominal 20K ohm value. This precision level suits general audio level adjustment and basic circuit trimming. The three-pin configuration supports standard voltage divider wiring for variable voltage control.

Replaces Single Fixed Resistors

This pack replaces fixed-value resistors when adjustable voltage division is required. The upgrade is worth it for audio stereo volume controls, radio receivers, or MP3 player circuits needing manual tuning. It is not for applications demanding tighter tolerance than +/-10% or automated digital control. The five-piece assortment covers multiple circuit points or provides spares for prototyping.

Questions about this item

Should I pick the 20K ohm version or look for a different resistance value?

The B203 model is supplied only in a 20K ohm resistance value with a +/-10% tolerance, so if your circuit calls for 20K this pack matches; otherwise you need a different model.

What does the 20K ohm rating mean when I install it in an audio volume control?

It provides a 20 kilohm total resistance range with linear change as you rotate the dial, giving predictable voltage division for stereo volume adjustment.

How does the three-pin interface limit the way I can wire this potentiometer?

The three pins give you the two end terminals and the wiper, allowing standard voltage-divider or rheostat wiring but no extra taps or switching functions.
