The HC-49S quartz crystal is a RoHS compliant crystal seamed sealed in a package, and it exhibits high precision, good reliability, tight frequency stability as well as wide frequency range (3MHz~100MHz). As a kind of low profile crystal, its height is only about one-fourth of that of HC-49U crystal, and the specific values are 3.5mm for 49S and 2.5mm for 49SS.
This quartz crystal unit is commonly utilized in UPS, computer, embedded system, security equipment, multimedia player, electromechanical device, vehicle-mounted device, small household appliance and so on.
