Temperature grade and environment
Rated for -40°C to 85°C, this RTC is suited for industrial enclosures, outdoor telecom pedestals, and factory-floor controllers where the ambient temperature swings beyond office-grade limits. The surface-mount 10-uMAX/uSOP footprint (3.00 mm width) keeps board area tight — a common constraint in panel-mount I/O modules and compact data loggers.
