Description
The CMR200T32.768KDZB-UT by Citizen Finedevice is a high-precision, miniature surface-mount crystal resonator engineered for the most demanding timing applications. Operating at a fundamental frequency of 32.768 kHz, this component is widely recognized as the industry standard for real-time clock (RTC) circuitry in sensitive devices like smart meters and high-end portable consumer electronics.
This crystal features a sophisticated reflowable cylinder-type package, which is specifically designed to withstand modern high-temperature surface-mount assembly processes without compromising performance. Its exceptionally compact dimensions—just 2.0 mm in diameter and 6.1 mm in length—make it the perfect choice for space-constrained PCB designs where reliability is non-negotiable. Furthermore, its extended operating temperature range of -40°C to +85°C guarantees stable timekeeping, even in harsh outdoor or industrial environments.
Key Features
- Precision Frequency: Tuned to 32.768 kHz, providing the exact clock reference needed for accurate real-time timekeeping.
- Industrial-Grade Thermal Range: Reliable operation from -40°C to +85°C, ensuring consistency in extreme weather or industrial settings.
- Reflow-Ready Design: The cylinder-type SMD structure is optimized for automated assembly, ensuring high yield and consistency in manufacturing.
- Miniature Footprint: Measuring only Φ 2.0 mm x L 6.1 mm, it helps you save critical board space in portable applications.
- High Stability: Features a tight frequency tolerance of ±20 ppm, minimizing time drift in your critical timing circuits.
