FILTRONETICS, Inc. designs and manufactures a complete array of filters, oscillators and crystals. 

HC-49 crystal

A piezo-electric quartz crystal is a stable, high Q resonator. Other names include; piezo-electric resonator, BAW resonator, and Crystal. Typical uses include timing applications, crystal filters, and crystal controlled oscillators. Some examples of a crystal oscillators are the clock oscillator, VCXO, TCXO, OCXO and VCTCXO.

Filtronetics Inc can supply fundamental crystals up to 200 MHz. Our quartz crystals can be in through hole or Surface mount (SMD) packaging. Through hole crystal packages include HC-13, HC-51, HC-48, HC-49, HC-45, UM-1, UM-3, UM-4, UM-5, 3 x 9 mm tubular, and 2 x 6 mm tubular. Surface mount crystal package includes 5 x 7 mm SMD, 3.5 x 6 mm SMD, HC-49 SMD, and UM-1 SMD. The practical frequency range for a quartz crystal is from 4 kHz to 600 MHz. Filtronetics, Inc utilizes flat, polished, fundamental, 3rd overtone, 5th overtone, and inverted mesa quartz crystal blanks in its crystal designs. Swept quartz for improved Q and reduced radiation affect is available. Typical cuts include AT-cut and BT-cut. Our quartz crystals have been utilized in space, military, undersea, airborne, testing, and commercial applications. We can produce from one to over a million quartz crystals for your application.

When specify a quartz crystal the following should be considered. We will be happy to discuss your particular application with you.

  1. Frequency
  2. Frequency tolerance at ambient
  3. Operating temperature.
  4. Frequency tolerance over operating temperature.
  5. Storage temperature
  6. Co or shunt capacitance
  7. C1 or motional capacitance
  8. L or motional inductance
  9. R or resistance
  10. Q or quality factor
  11. Pullabilty
  12. Drive level
  13. Mode of operation (fundamental, 3rd or 5th overtone)
  14. Aging
  15. Series mode or series capacitance
  16. Insulation resistance
  17. Shock and Vibration requirements
  18. Package requirements (HC-13, HC-51, HC-48, HC-49, HC-45, UM-1, UM-3, UM-4, UM-5, 3 x 9 mm tubular, and 2 x 6 mm tubular, 5 x 7 mm SMD, 3.5 x 6 mm SMD, HC-49 SMD, and UM-1 SMD)
