Description
The 45 Series SMT consists of a silver-
plated AT-cut quartz crystal plate, en-
capsulated in a nitrogen-filled metal
holder. The holder is hermetically sealed
by resistance welding. The device has a
very high mechanical stability, small
dimensions and rugged construction.
Applications
• Microprocessors
• Traffic Control
• Weather Ballons
• Medical systems
• Military applications
• Communications systems
• Agrarian applications
• Machine control
