THROUGH-HOLE CRYSTALS

HC49/4H CRYSTALS

DESCRIPTION

HC49/4H crystals share the same base dimensions as the industry-

standard HC49 crystal but with a low profile can. The crystal utilizes an

AT-cut strip crystal with a hermetically sealed metal can. HC49/4H

crystals provide a low-cost solution for many applications, particularly

where PCB height is restricted.
