CX-3V-SM CRYSTAL

18 kHz to 600 kHz

Miniature Surface Mount

Quartz Crystal for Pierce Oscillators

DESCRIPTION

actual size

side view

The CX-3V-SM quartz crystals are leadless devices

designed for surface mounting on printed circuit boards

or hybrid substrates. These miniature crystals are

intended to be used in Pierce oscillators. They are

hermetically sealed in a rugged, miniature ceramic

package. They are manufactured using the STATEK-

developed photolithographic process, and were

designed utilizing the experience acquired by producing

millions of crystals for industrial, commercial, military and

medical applications. Maximum process temperature

should not exceed 260^OC.
