Low aging, high precision SMD crystals for RF clock applications

Low aging, high precision SMD crystals for RF clock applications ACT now offer RF clock reference crystals fully optimised for RF/wireless and all other demanding applications requiring tight frequency stability, tolerance and low aging.

Long term-stability

The various packages consist of high quality SMD crystals in a ceramic base/metal lid, seam sealed for long-term stability. The lid is grounded via the conductive seal to the spare pads on the base, which assists overall EMI reduction.

Fully optimised for demanding applications

The crystals are fully optimised for RF clock/wireless applications and meet the tight frequency control demands of Bluetooth®, Zigbee® and other WLan/ISM band low power radio applications.


  • High precision and quality
  • Low aging and long term stability
  • Fully optimised for RF/Wireless applications
  • Competitively priced to meet cost/performance ratios
  • Available in industry standard sizes to fit most applications (5.0 x 3.2mm, 3.2 x 2.5mm, 2.5 x 2.0mm, 2.0 x 1.6mm, 1.6 x 1.2mm)


  • First year aging at ±1ppm at 25°C
  • ±10ppm Frequency tolerance at 25°C
  • Operable temperature range of -40 ~ +85°C
  • ±10ppm stability over extended temperature range -30 ~ +85°C
  • Common RF/wireless frequencies fully developed (depending on package size required)
