Product details
The QT49-18.432MBBK-B from QST 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 MHz Crystal oscillator incorporates corrosion-resistant materials that outperform standard components in high-humidity marine applications.Operating at 18.432 MHz, the device provides stable references for AIS transponders and electronic chart display systems.With ±50ppm stability, it maintains precision despite temperature variations encountered from polar waters to tropical climates.The ±50ppm tolerance ensures reliable operation in dynamic positioning systems and autonomous marine vehicles.Engineered with 20pF load capacitance, it compensates for cable capacitance variations in distributed marine radar systems.The 30 Ohms 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 -20°C ~ 70°C, the component performs reliably in both surface vessels and deep-sea ROVs.The Through Hole configuration incorporates conformal coating compatibility for additional environmental protection.Housed in a HC-49/US package, it meets IP68 standards for waterproof operation in splash zones and wet locations.With 0.453" L x 0.197" W (11.50mm x 5.00mm) dimensions, the compact design enables installation in space-constrained bridge equipment.The 0.145" (3.68mm) low profile accommodates installation in slim marine displays and control panels.
