CX3SM AT CRYSTAL

Low Profile Miniature SMD Crystal

9.6MHz to 250MHz

FEATURES

Designed for surface mount applications, including

infrared, vapour phase or epoxy mount techniques

Hermetically sealed ceramic package

Excellent ageing characteristics

Available with glass or ceramic lid

High shock and vibration resistance

Custom designs available

DESCRIPTION

CX3SM AT crystals in leadless ceramic packages are designed for

surface mounting on PCB or hybrid substrates. The small footprint,

low profile crystal is ideal for a wide range of commercial, industrial,

medical and defence/aerospace applications.
