OUTLINE & DIMENSIONS
DESCRIPTION
CX9VSM crystals are leadless devices designed for surface mounting
on PCBs or hybrid substrates. The crystals have a very low-profile
(<0.94mm) and are suited for all low frequency applications.
SPECIFICATION
Specifications stated are typical at 25°C unless otherwise indicated.
Specifications may change without notice.
