General Description
CX-3-SM AT-cut crystals are leadless devices designed for surface-
mounting on printed circuit boards or hybrid circuits. The crystals
are low profile with a very small land area.






Designed for surface-mount applications using
infrared, vapour phase, wave solder or epoxy
mount techniques
Ideal for use with microprocessors
Designed for low power applications
Compatible with hybrid or PCB mounting
Low ageing
Full military environmental testing available
Custom designs available
