DESCRIPTION

CX3HGSM AT crystals in leadless ceramic packages are designed for

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

low profile crystal has been designed for applications requiring high

shock and vibration survival.

FEATURES

Very high shock and vibration survival

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

Custom designs available

Full Military testing available

PACKAGING OPTIONS

CX3HGSM AT crystals are available either tray packed (<250pcs) or

tape and reel (>250 pieces).

16mm tape, 178mm or 330mm reels (EIA 418).
