It delivers a 12 MHz CMOS output with ±25 ppm frequency stability, running from a 1.7V to 3.6V supply rail — the wide voltage range lets it share a rail with 1.8V or 3.3V logic without an extra regulator. ## Standby power-down — 15 µA disable current for battery-backed designs For a telematics module or sensor node that clocks most of its life in sleep, that 15 µA leakage is below the self-discharge of a small coin cell — the oscillator does not drain the backup battery. ## 4-SMD no-lead package — surface-mount layout fit Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, it fits standard 5x3.2 mm XO footprints — a drop-in replacement for quartz oscillators in that form factor.","metaTitle":"DSC1003BE2-012.0000 – Microchip MEMS XO, 12 MHz, AEC-Q100","metaDescription":"Active Microchip DSC1003BE2-012.0000 – 12 MHz MEMS XO with AEC-Q100 qualification, ±25 ppm stability, standby power-down, 1.7-3.6 V supply.","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":"DSC1003","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"12 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"1.7V ~ 3.6V","Base Product Number":"DSC1003","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"6mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1003BE2-012.0000 AEC-Q100 qualified?","answer":"Yes — the ratings field lists AEC-Q100 qualification, meaning it has passed the automotive-grade temperature cycling, ESD, and reliability stress tests. It is suitable for engine-bay and cabin electronics within its -20°C to +70°C operating range."},{"question":"What is the standby power-down function on the DSC1003BE2-012.0000?","answer":"The standby (power-down) function disables the output and reduces supply current to 15 µA max from 6 mA max active. It lets the system gate the clock to save power in sleep or idle modes without removing the supply rail."},{"question":"Can the DSC1003BE2-012.0000 replace a quartz crystal oscillator?","answer":"Yes — as a MEMS-based XO, it is a direct functional replacement for a quartz oscillator in the same 4-SMD no-lead footprint and supply voltage range. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which is relevant for automotive and industrial environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1003BE2-012.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1003BE2-012.0000 when reusing this data.
