LFXTAL003074 Frequently Asked Questions (FAQs)

  • IQD Frequency Products recommends a symmetrical layout with the crystal centered on the PCB, and the traces to the oscillator circuit should be as short as possible to minimize noise and radiation.
  • Handle the crystal by the edges or the package, avoid touching the metal surfaces, and use an anti-static wrist strap or mat to prevent electrostatic discharge (ESD) damage.
  • Use a soft brush and a mild detergent solution to clean the crystal, and avoid using ultrasonic cleaning or harsh chemicals that can damage the crystal or its packaging.
  • Store the crystals in their original packaging, away from direct sunlight, moisture, and extreme temperatures, and avoid stacking or bending the crystals during storage.
  • The expected lifespan of the LFXTAL003074 crystal is typically 10 to 20 years, depending on the operating conditions, storage, and handling practices.
