The 4-SMD no-lead package (3.20 mm x 2.50 mm footprint, 0.90 mm seated height) is a standard 4-pin oscillator layout — no special fan-out or via-in-pad needed; it reflows on a standard profile and drops into most 33.33 MHz clock sockets without a board spin.
It fits under-hood and cabin domains where a commercial-grade part would risk field returns from thermal cycling or vibration.
Supply voltage flexibility and current draw
Operates from 1.8V to 3.3V — the wide supply range means it can run directly off a 1.8V core rail or a 3.3V I/O rail without an extra regulator. The 7.2 mA max supply current at 33.33 MHz is modest; the thermal budget is not an issue in the 4-SMD package.
