The 27 MHz frequency is common for USB, Ethernet PHY reference clocks, and MCU main oscillators. ## Industrial temperature grade and standby power Use it in outdoor telecom enclosures, factory-floor controllers, engine-bay electronics, or any environment where a commercial-grade (0-70°C) oscillator would drift or fail. For a battery-powered sensor node that sleeps most of the time, this keeps the oscillator's own draw negligible against the battery self-discharge. Active current is 10 mA max at 27 MHz. 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max.","metaTitle":"DSC1033CI2-027.0000T MEMS XO, 27 MHz, CMOS","metaDescription":"DSC1033CI2-027.0000T: Microchip PureSilicon™ MEMS oscillator, 27 MHz, CMOS output, ±25 ppm stability, 3.3 V, industrial temp.
