ACT HC49/US-SMX ( Standard 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 its wide range of specification options, the HC49/US-SMX is a favoured
choice in many applications, including Communications, Industrial Controls, Microprocessor Systems,
Vending, Security and Access Control. There are four height options available ranging from 2.7 to 4.2
mm max.
