It uses a 3-wire Up/Down serial interface (U/D, INC, CS) for wiper positioning, and the non-volatile memory retains the last wiper setting after power is removed. With 100 taps across 10kΩ, each step is approximately 101 Ω, giving fine-grained adjustment for applications like audio gain staging, sensor offset trimming, or programmable voltage references. The ±20% end-to-end tolerance is typical for a digital pot — the ratiometric accuracy between taps is what matters for the divider function. This limits deployment to indoor, office, or lab environments — not automotive or extended industrial. The temperature coefficient is ±300 ppm/°C typical, which means the absolute resistance drifts about 3 Ω per °C at 10kΩ, but the tap-to-tap ratio stays stable enough for most trim applications. The wiper resistance is 40 Ω typical, which sets the minimum voltage drop from wiper to the resistor string. In low-impedance loads this can be a significant fraction of the output, so budget it into the divider calculation. ## Package and board-fit Housed in an 8-SOIC narrow-body package (3.90 mm width, 0.154\" pitch), the X9318WS8Z uses a standard surface-mount footprint. The supplier device package is also 8-SOIC, so no footprint variation between the generic and branded package codes. Supplied in tube packaging, not tape-and-reel — factor this into pick-and-place setup if ordering in volume.","metaTitle":"X9318WS8Z 10kΩ 100-Tap Digital Potentiometer, 8-SOIC","metaDescription":"X9318WS8Z 10kΩ digital pot, 100 taps, non-volatile, 5V supply, 8-SOIC.
