ACT631SMX-4
The
ACT631SMX-4
is a 4 pad, high quality, low aging, metal seam, packaged crystal suitable for automatic
placement on printed circuit boards. It utilises a ceramic base and metal lid for durability. the lid is grounded
through the package and the pads are gold plated. With a wide frequency range, and tight stability it has become
one of the optimum choices for design engineers.
Applications
include Communications, Microprocessor
Systems, Instrumentation and many more.
