Quartz crystals - photoQuartz crystals

International Crystal Manufacturing (ICM) manufactures a broad line of custom quartz crystals. Quartz crystals are thin slices of quartz placed between two electrodes, housed in a hermetically sealed package that provides a means of connection to a circuit. An alternating voltage applied to these electrodes causes the quartz to vibrate, or oscillate, at a particular frequency.

The frequency is a function of the thickness of the crystal. By carefully polishing or lapping a crystal, it can be made to oscillate at any frequency. ICM manufactures our quartz crystals using tight production controls based on our ISO 9001:2008 certification procedures.

Quartz crystal product types

ICM offers three major categories of quartz crystals:

  • Thru hole crystals - leaded holder typically manually installed used for more demanding applications than surface mount crystals.

  • Surface mount crystals - leadless components designed for pick and place or automatic installation

  • Microprocessor crystals - wide tolerance, cost-effective crystals, used for general timing applications on fixed frequencies.


ICM custom quartz crystals typically have frequency ranges of 32.768 KHz to 200 MHz. If your application requires higher frequencies, please contact our crystal engineers at 1-800-725-1426.

Typical applications

Quartz crystals are basically used for accurate timing and frequency control. Quartz crystal applications include:

  • Security cameras in airplane cargo bays
  • Radio transmitters for tracking salmon, whales and other wildlife
  • Meters in gas pumps
  • Utility meters attached to your home
  • Cell phones
  • Satellite communications
  • WAN/LAN equipment
  • Test instruments on the bench
  • Instruments at the bottom of oil wells
