The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which is why this part carries AEC-Q100 qualification."},{"question":"Is the DSC1121CL2-040.0000 AEC-Q100 qualified?","answer":"Yes — the DSC1121CL2-040.0000 carries an AEC-Q100 rating, meaning it has passed the automotive-grade temperature cycling, ESD, and reliability stress tests. It is suitable for under-hood and chassis-domain ECUs where the ambient temperature reaches 105°C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CL2-040.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CL2-040.0000 when reusing this data.
