The 3.3V supply rail and ±50ppm frequency stability suit general-purpose clocking in industrial-temperature environments (-40°C to +85°C). The Standby (Power Down) function drops supply current to 1µA max when disabled, useful for battery-operated equipment that gates the clock during sleep. ## Package and board-fit note Housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. The 0.098\" x 0.079\" footprint is common among MEMS oscillators in this frequency range; verify pad layout against the datasheet land pattern before committing a board spin. ## Power consumption profile Active current is 3mA typ at 12 MHz – negligible for most digital loads. The standby current of 1µA max means the oscillator's own draw is below the leakage floor of many battery-powered designs, so the power-down pin effectively gates the clock without a separate load switch.","metaTitle":"DSC1033DI1-012.0000 MEMS Oscillator – 12 MHz CMOS, 3.3V","metaDescription":"Microchip DSC1033DI1-012.0000 XO (Standard) MEMS oscillator, 12 MHz CMOS output, 3.3V, ±50ppm, -40°C~85°C.
