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
