The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm footprint shared by many MEMS and quartz oscillators, so the PCB layout can accept alternate suppliers without a spin. Surface-mount assembly with no through-hole leads; the small footprint suits space-constrained automotive modules like camera or radar sensor boards. Sourced through independent distribution against the BOM quantity.","metaTitle":"DSC1121CI1-125.0000T – Microchip 125 MHz MEMS XO, CMOS","metaDescription":"DSC1121CI1-125.0000T – Microchip DSC1121 series MEMS oscillator, 125 MHz CMOS output, 2.25-3.6V supply, AEC-Q100 rated, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121CI1-125.0000T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1121CI1-125.0000T AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating, which means it meets automotive-grade reliability stress and temperature qualification.
