Miniature tuning fork design

High shock resistance

Designed for low power applications

Compatible with hybrid or PCB mounting

Low ageing

General Description

Full military environmental testing available

Ideal for battery operated applications

The CX-3H-SM quartz crystals are leadless devices designed for

surface-mounting on printed circuit boards or hybrid circuits.

These miniature crystals are intended for use with series

oscillators. Hermetically sealed in a rugged, ceramic package, the

crystals are produced utilizing a photo-lithographic process giving

excellent repeatability and consistent high quality.
