ACT HC49/US-SMX (Custom Packages)
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.
