Description
The LFXTAL002997 is a premium 32.768 kHz quartz crystal resonator housed in a miniature 6mm x 2mm cylindrical radial package. This component is the industry standard for precision timekeeping and real-time clock (RTC) applications where board space is at a premium.
Engineered to provide high reliability, it operates effectively within a broad thermal range of -40°C to +70°C. Its fundamental frequency of 32.768 kHz is specifically chosen because it is a power-of-two fraction of one second ($2^{15}$ Hz), making it perfect for driving clock counters and keeping accurate time in low-power, battery-operated devices.
Key Features
- Precision Timing: 32.768 kHz fundamental frequency ensures accurate timekeeping for RTC circuits.
- Ultra-Compact Design: 6mm x 2mm dimensions make it ideal for highly integrated or wearable electronics.
- Wide Thermal Range: Reliable performance from -40°C to +70°C, suitable for diverse operating environments.
- Standardized Load: 12.5 pF load capacitance is compatible with the majority of RTC oscillators in microcontrollers.
Application
- Real-Time Clock (RTC) Modules
- IoT Wearable Devices and Trackers
- Battery-Powered Industrial Timers
- Data Logging Equipment
Package Includes
- 2 x LFXTAL002997 32.768 kHz Crystal
