The DSC1033DI1-012.2880T: The 4-SMD no-lead package (2.50mm x 2.00mm) sits on a standard reflow profile — no special handling beyond the usual MSL bake if the reel seal is broken.
Typical active current is 3mA max at 3.3V — the MEMS resonator consumes less than a quartz-based XO at the same frequency, which matters in a tight power budget.
This is a standard stability grade for industrial-grade oscillators — adequate for UART bit-rate clocks and most processor reference inputs.
