Low-profile crystal units

Low-cost, industry-standard crystal unit

AT-Cut strip crystal with hermetically sealed can

Frequency range 3.2MHz to 70MHz

Package height options available

DESCRIPTION

HC49-4H and HC49-4HL Crystals

OUTLINES & DIMENSIONS

HC49-4H crystals have the same base outline as the industry-

standard HC49 crystal. The crystal uses at AT-cut strip crystal with an

hermetically sealed can. HC49-4H crystals provide a low cost source

of system clock frequency.
