The CSM-7 is an excellent choice for the SMD

version of the HC-49US leaded crystal. The

CSM-7 has a case height of 4.3 mm maximum

in a resistance weld metal package. A package

profile of 3.2 mm maximum is also available.

FEATURES

• Cost effective

• Space saving design

• Low profile

• Tape & Reel (1,000 pcs)
