The ACT HC49/US-SMX is one of the most cost effective and popular surface mount crystals available. With

it’s wide range of frequencies, stabilities and operating temperatures it is still small enough to fit most

applications including many hand held units and is the economical solution for automatic assembly. With it's

available tight tolerances / stabilities and available operating temperature ranges, the HC49/US-SMX is a

favoured choice in many applications, including Communications, Industrial Controls, Microprocessor Systems,

Vending, Security and Access Control.
