Package and footprint for 4-SMD no-lead layout
The 5.00 mm × 3.20 mm body with a seated height of 0.90 mm is the standard 5×3.2 mm oscillator footprint. The 4-SMD no-lead package has four castellations on the bottom — no side pads — so the PCB land pattern uses a simple rectangular pad per terminal. No via-in-pad needed. Surface-mount assembly with the 0.90 mm profile fits under shielding cans or low-profile enclosures. The MEMS die inside is encapsulated, so no hermetic seal is required — the plastic package is standard for automotive ambient humidity.
The DSC1001 series is the base product number; the full suffix encodes the stability grade, temperature range, and output type, so a BOM change to a different frequency or stability requires a different suffix, not a different series. No stock-holding claim; the part is procured per order.
