ACT531SMX-4
The
ACT531SMX-4
is a 4 pad, high quality, low aging, seam welded packaged crystal. Utilising a ceramic
base with a metal lid, it provides for the durability and reliability, necessary for strenuous processes like
infrared and vapour reflow. The lid is grounded through the package and the pads are gold plated. The
device is very suitable for automatic placement on PCB's. With an excellent range of frequencies and
stabilities it has become one of the optimum choices for design engineers.
Applications
include
Communications, Microprocessor Systems, Instrumentation and particularly Wireless Communications
applications. Available loose or on 1,000pc reels.
