OPERATING CONDITIONS / ELECTRICAL CHARACTERISTICS
The CSM-7X is an excellent choice for a low cost SMD Crystal. The CSM-7X (5PX)
has a case height of 4.3 mm Max. in a resistance weld metal package. Lower
profile package height of 3.2 mm is available with the (5PLX) package.
• Cost Effective
• Low Profile
• Industry Standard Footprint
• Pb Free/RoHS Compliant
