Product Description
WH5 potentiometers provide a continuous resistance track with A, B or C taper and a nominal resistance tolerance of plus or minus 20%, and this listing covers values from 5 kOhm to 10 kOhm. The carbon-film track and metal-shaft construction suit volume, gain and set-point adjustment on control panels and audio equipment. Rated operating voltage is up to 150 V AC or 200 V DC depending on taper, with a rotational life of around 10,000 cycles. The Bettomshin WH5-II-1W is a single-turn rotary potentiometer from the WH5 family, a widely used panel-control variable resistor offered here in a 1 W power variant.

Technical Specifications
Version & Model Difference
The WH5-II-1W is a variant of the WH5 single-turn rotary potentiometer family; the -1W suffix denotes the 1 W power rating and II the body/shaft style. WH5 potentiometers are available in different resistance values, tapers (A/B/C) and shaft types, so the exact resistance and taper should be confirmed against the required part before ordering.
Application Scenarios
- Volume, gain and tone adjustment in audio equipment
- Set-point and trimming adjustment on control panels
- General-purpose educational and hobby electronics
