Product details
Citizen Finedevice Co Ltd's CM250S77.503KAZFT Crystals redefines power efficiency for energy harvesting applications, optimized to operate with minimal current draw while maintaining exceptional timing accuracy. Designed for self-powered IoT sensors and wearable devices, it enables years of maintenance-free operation from ambient energy sources.As a kHz Crystal (Tuning Fork) device, it incorporates novel circuit architectures that reduce startup voltage requirements compared to conventional oscillators.Supporting 77.503 kHz operation, the crystal provides stable timing for energy-aware wireless protocols like LoRaWAN and NB-IoT.With ±30ppm tolerance, it maintains synchronization in sparse wake-up scenarios typical of energy-neutral operation.Optimized with 12.5pF load capacitance, it minimizes power consumption during sleep modes while enabling rapid wake-up transitions.The ultra-low 50 kOhms ESR enables operation from micro-energy sources like piezoelectric harvesters and small solar cells.Employing Fundamental technology, it achieves sub-threshold operation compatible with energy-constrained environments.Designed for -40°C ~ 85°C, the component performs reliably in both indoor environmental sensors and outdoor agricultural monitors.The Surface Mount design facilitates automated assembly while withstanding mechanical stress in embedded sensor applications.The 4-SOJ, 5.50mm pitch package enables direct integration with energy harvesting power management ICs in compact designs.With 0.311" L x 0.146" W (7.90mm x 3.70mm) dimensions, it fits the most space-constrained layouts in smart building sensors and industrial condition monitors.The 0.098" (2.50mm) ultra-slim profile enables integration into paper-thin flexible electronics and smart labels.
