The AEC-Q100 rating means this part passed automotive-grade reliability stress — a common requirement for engine-control modules, transmission controllers, and body electronics that see temperature swings and vibration. Microchip lists the DSC1121CE2-066.6600T as Active. ## 6-SMD footprint and supply-range flexibility The 6-SMD, No Lead package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts. The wide supply range (2.25 V – 3.6 V) allows the same BOM entry to serve multiple voltage domains, reducing line-item count.","metaTitle":"DSC1121CE2-066.6600T MEMS Oscillator 66.66 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121CE2-066.6600T XO (Standard) MEMS oscillator, 66.66 MHz CMOS output, AEC-Q100 qualified, -20°C to 70°C, 2.25V-3.6V supply, 6-SMD package.","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":"66.66 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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°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/DSC1121CE2-066.6600T/alternatives.json"},"ai":{"faq":[{"question":"How can I order the DSC1121CE2-066.6600T or request a quote?","answer":"Submit your target quantity and delivery timeline — we confirm availability and current pricing at quote time, sourced through our independent distribution channel."},{"question":"Is the DSC1121CE2-066.6600T AEC-Q100 qualified?","answer":"Yes, the DSC1121CE2-066.6600T is rated AEC-Q100, which means it passed automotive-grade IC qualification including temperature cycling, ESD, and reliability stress.
