The no-lead construction means the terminations are flush with the package body — the PCB footprint must match the land pattern exactly; there are no protruding leads to absorb board flex. Surface-mount reflow is standard, and the small footprint suits dense layouts.","metaTitle":"DSC1121CM5-033.3333 MEMS XO, 33.3333 MHz, CMOS","metaDescription":"Microchip DSC1121CM5-033.3333 XO (Standard) MEMS oscillator, 33.3333 MHz CMOS output, ±10ppm stability, 2.25V-3.6V supply, -55°C to 125°C, AEC-Q100.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"33.3333 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for DSC1121CM5-033.3333?","answer":"Microchip has not listed an official successor or pin-compatible cross reference for this order code.
