Miniature tuning-fork design

High shock resistance

Designed for low-power applications

Compatible with hybrid packaging

Low ageing

General Description

The CX-1V quartz crystal is a high quality tuning fork resonator

designed for use in Pierce (single inverter) oscillators. The CX-1V is

hermetically sealed in a rugged, miniature ceramic package, a

quarter the size of an eight pin dual-in-line package. The crystal is

manufactured utilizing a photo-lithographic process, ensuring

consistency and repeatability of electrical characteristics.

Full military environmental testing available

Ideal for battery powered applications
