SURFACE-MOUNT CRYSTALS
90SMX(SH) CRYSTALS
9mm x 3.8mm x 2.5mm
DESCRIPTION
90SMX(SH) crystals utilize the standard 90SMX package but with AT-Cut
crystal blanks, providing a compact crystal with the frequency range of
12MHz to 40MHz.The crystals have a low-profile and are manufactured in
epoxy resin.
