CSM-7
SMD QUARTZ CRYSTAL
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)
