Product details
The CM21232768DZFT from Citizen Finedevice Co Ltd sets new benchmarks for Crystals in marine navigation systems, specifically designed to withstand saltwater corrosion and maintain timing accuracy in challenging maritime environments. Its ruggedized construction and exceptional frequency stability make it ideal for GPS augmentation systems and sonar equipment.This kHz Crystal (Tuning Fork) oscillator incorporates corrosion-resistant materials that outperform standard components in high-humidity marine applications.Operating at 32.768 kHz, the device provides stable references for AIS transponders and electronic chart display systems.The ±20ppm tolerance ensures reliable operation in dynamic positioning systems and autonomous marine vehicles.Engineered with 12.5pF load capacitance, it compensates for cable capacitance variations in distributed marine radar systems.The 90 kOhms ESR characteristic remains stable despite prolonged exposure to salt spray and moisture.Utilizing Fundamental operation, it achieves the necessary spectral purity for multibeam echosounder applications.Rated for -40°C ~ 85°C, the component performs reliably in both surface vessels and deep-sea ROVs.The Surface Mount configuration incorporates conformal coating compatibility for additional environmental protection.Housed in a 2-SMD, No Lead package, it meets IP68 standards for waterproof operation in splash zones and wet locations.With 0.079" L x 0.047" W (2.00mm x 1.20mm) dimensions, the compact design enables installation in space-constrained bridge equipment.The 0.024" (0.60mm) low profile accommodates installation in slim marine displays and control panels.
