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.
