Description
The crystals are miniature AT or BT cut
strip resonators housed in low profile
packages for surface mounting. The parts
present a proven metal package techno-
logy with a precision molded base and
universal contact configuration.
Applications & Features
• Low profile SMD
• AT or BT cut performance
• Resistance weld seal
• 49SNC is interchangable with popular
molded crystal configurations
• Available on tape & reel; 24mm tape,
1000pcs per reel
