Operating from 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V core rail or a 3.3V I/O rail without an external regulator — the same BOM line works across both domains. Housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, it fits the standard 5x3.2mm oscillator footprint used in many automotive ECUs and industrial controllers. Maximum supply current is 6.5mA — low enough that the thermal rise in the SMD package is negligible, even in a densely populated board with limited airflow.

Frequently asked questions
Is DSC1001BI1-012.0000 AEC-Q100 qualified?
Yes — the ratings field lists AEC-Q100 qualification. This means the oscillator has passed automotive-grade stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood and chassis-domain applications where commercial-grade oscillators would not be accepted.
