The part ships in Tape & Reel (TR) packaging, 6-SMD no-lead footprint, 3.20 mm x 2.50 mm body with 0.90 mm seated height — a standard MEMS oscillator footprint that drops onto a two-layer board without via-in-pad. Maximum supply current is 22 mA at full load — the actual draw depends on the output frequency and load capacitance; at 8 MHz into 15 pF it typically runs well under that ceiling.","metaTitle":"DSC1121CI2-008.0000T 8 MHz MEMS Oscillator – Microchip","metaDescription":"DSC1121CI2-008.0000T: 8 MHz XO, CMOS output, ±25 ppm stability, 2.25V–3.6V supply, -40°C to 85°C, 6-SMD.
