CX6SM AT CRYSTAL

Ultra Miniature Low Profile 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

DESCRIPTION

Available with glass or ceramic lid

Higjh shock and vibration resistance

Custom designs available

CX6SM AT crystals in leadless ceramic packages are designed for

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

low profile, ultra-miniature crystal is ideal for a wide range of

commercial, industrial, medical and defence/aerospace applications.

Full Military testing available

CRYSTAL EQUIVALENT CIRCUIT

1. Other tolerances available, contact Euroquartz sales.

2. Unless specified otherwise.

3. Does not include calibration tolerance. The characteristics of the

frequency stability over temperature follow that of the AT thickness-

shear mode.

4. 10ppm max. for frequencies below 40MHz For tighter tolerances

and higher frequencies contact Euroquartz sales.

5. Higher shock version available.

6. Per MIL-STD-202G, Method 204D, Condition D. Random vibration

testing also available.
