Non-volatile memory retains the wiper setting after power-down, eliminating the need for a separate EEPROM or microcontroller re-initialization routine on each power-up. The Up/Down (U/D, CS) interface uses two digital lines for wiper position control, simplifying firmware integration compared to SPI or I²C alternatives. ## Industrial temperature grade and supply flexibility The SOT-23-6 package (supplier device package SOT-23-6) occupies minimal board area — approximately 2.9 mm × 1.6 mm — and is compatible with standard reflow soldering profiles. ## Wiper resistance and temperature coefficient impact on accuracy Typical wiper resistance is 70 Ω, which adds to the programmed resistance value and sets a floor on the minimum achievable resistance between wiper and terminal B. Temperature coefficient of 150 ppm/°C means the resistance drifts by 0.75 Ω per °C at the 5 kΩ full-scale setting — acceptable for bias and adjustment circuits but relevant for precision divider applications requiring better than 1% stability over temperature. Resistance tolerance is ±20%, so the absolute end-to-end resistance of a given unit may range from 4 kΩ to 6 kΩ; this must be accounted for in the circuit design if the absolute resistance value is critical.","metaTitle":"Microchip MCP4023T-502E/CH Digital Potentiometer, 5kΩ","metaDescription":"Microchip MCP4023T-502E/CH digital potentiometer, 5kΩ linear taper, 64 taps, non-volatile memory, SOT-23-6, -40°C to 125°C.
