Product description 2 Set WTH118 100K Potentiometer Kit, Single Turn Rotary Carbon Variable Potentiometers with Knobs Nuts Washers Dials for DIY Electronics Audio Equipment What is this? This single-turn rotary carbon variable potentiometer kit is designed for precise resistance adjustment in electronic circuits. The WTH118 potentiometers are commonly used in audio equipment, DIY electronics projects, and industrial control systems where smooth resistance variation is required. What will I get? WTH118 Potentiometer Knob Caps Color: Black Pin Count: 3; Nominal Resistance: 100K; Power Rating: 2W Rotation Angle: 270° Handle Dimensions: 10 x 6mm / 0.39 x 0.24inch (LxD); Potentiometer Size: 28 x 15mm / 1.1 x 0.59inch(LxH); Package Includes: 2 x Carbon Potentiometers, 2 x Knob Caps, 2 x Nuts, 2 x Washers, 2 x Dials Are there any advantages of the product? The potentiometer kit features carbon film technology, providing stable performance and smooth resistance adjustment. The thickened iron shell offers improved durability and corrosion resistance compared to standard plastic housings. Copper components with silver contacts ensure better conductivity and sensitivity during operation. With a mechanical lifespan of 100,000 rotations, these single-turn rotary potentiometers maintain consistent performance over extended use, while the ±10% resistance tolerance meets the requirements of general electronic applications. How to use it? To install the potentiometer, first identify the pins by measuring resistance between terminals - the two pins showing maximum resistance are fixed ends, while the remaining pin is the sliding contact. Connect the sliding terminal to one fixed end, creating an adjustable resistance between this connection and the other fixed terminal. What should I notice? Different WTH118 series models may have varying specifications, so confirm the ohm rating matches your requirements before installation.
