Frequently Asked Questions
How many wiper positions does MCP4141-103E/P support, and what resistance step does each increment provide?
MCP4141-103E/P provides 129 linear wiper positions across a 10 kΩ end-to-end resistance. Each single increment or decrement step changes resistance by approximately 78 Ω, allowing fine-grained analog control for audio attenuation, programmable gain, and precision voltage divider applications in embedded systems.
Does the MCP4141-103E/P retain its wiper setting after the system is powered off?
Yes. MCP4141-103E/P includes non-volatile memory that stores the wiper position even when power is removed. This means the 10 kΩ potentiometer will power up at its last programmed resistance without requiring any SPI command from the host microcontroller, reducing firmware overhead in consumer and industrial products.
What is the procurement lead time and RoHS compliance status for MCP4141-103E/P?
MCP4141-103E/P has a factory lead time of approximately 8 weeks and carries full RoHS compliance with a Pb-free JESD-609 e3 rating. It is supplied in PDIP-8 through-hole format; buyers requiring surface-mount assembly should evaluate the MCP4141 in SOIC-8 or TSSOP-8 packaging, which share the same single-channel SPI digital potentiometer architecture.
