Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1033BI1-012.0000 fits standard 5x3.2 mm oscillator footprints. The no-lead construction eliminates side-castellation solder joints; the pad layout under the body should match the recommended land pattern for 4-pin ceramic SMD oscillators to avoid tombstoning during reflow. Surface-mount assembly with the 0.90 mm profile clears typical board-to-board clearance constraints in stacked mezzanine designs. No external load capacitors are required — the MEMS resonator and output driver are self-contained. ## Sourcing posture and lifecycle","metaTitle":"DSC1033BI1-012.0000 Microchip MEMS XO 12 MHz CMOS - Active","metaDescription":"DSC1033BI1-012.0000 Microchip PureSilicon™ XO, 12 MHz, CMOS output, ±50 ppm, -40°C to 85°C, 3.3V, 4-SMD.
