The disable current is low enough that a small coin cell or supercap can hold the oscillator in standby for extended periods without draining the main battery.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — this is a standard MEMS oscillator footprint that matches many quartz XO pinouts, so a board designed for a 2.5 x 2.0 mm crystal oscillator can accept this part without layout changes. Surface-mount assembly with a no-lead package means the solder joints are under the body — ensure the PCB land pattern matches the recommended footprint for 4-SMD parts to avoid tombstoning during reflow.
