This is useful for battery-powered ECU modules that sleep between wake-up events. The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This compact footprint matches standard 3.2 x 2.5 mm XO land patterns, making it a drop-in replacement for many quartz oscillators of the same size.","metaTitle":"DSC1001CI5-012.5000T MEMS XO – 12.5 MHz, ±10 ppm, AEC-Q100","metaDescription":"Buy DSC1001CI5-012.5000T: Microchip MEMS XO, 12.5 MHz CMOS output, ±10 ppm stability, -40°C to 85°C, AEC-Q100.

The MEMS resonator gives better shock/vibration tolerance, which matters for automotive or industrial applications. Check the supply voltage range (1.8V to 3.3V) and the 4-SMD footprint to confirm it matches your existing PCB land pattern."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI5-012.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI5-012.5000T when reusing this data.
