Features
-32.768 kHz is the standard frequency for real-time clock (RTC) applications, commonly used in embedded systems, clocks, and watches.
-SMD (Surface-Mount Device): It’s designed for easy mounting directly onto a PCB (printed circuit board), suitable for automated assembly processes.
-The drive level is the power supplied to the crystal to excite it to oscillate. It's generally low for 32.768 kHz crystals, often around 1 µW to 100 µW.
-Typically, crystals have an aging rate of ±5 ppm/year or less, meaning the frequency may shift slightly over time due to factors like temperature and stress.
