EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE CRYSTALS 10.7mm x 4.7mm x 2.0mm SMD

DESCRIPTION

The MS2 crystal provides an ideal source of low frequency clock signals (under 10MHz) in a low-profile SMD package height of 2.0mm. The crystal features a glass to metal substrate and resistance- welded metal lid offering enhanced hermetic properties. Premium grade AT-strip crystal plate is mounted at both ends for high shock and low g sensitivity.

  • Low height SMD package for low frequencies
  • Frequency range 3.2MHz to 70.0MHZ
  • Fully RoHS compliant
  • Standard EIA tape and reel OUTLINE & DIMENSIONS Frequency Range AT-Cut Fundamental: 3.2MHz to 30.0MHz AT-Cut 3rd Overtone: 27.0MHz to 70.0MHz BT-Cut Fundamental: 24.0MHz to 48.0MHz Calibration Tolerance at 25ºC*: from ±10ppm at 25°C (±30ppm standard) Frequency stability AT-Cut: ±30ppm over-10° to +60°C BT-Cut: ±100ppm over -10° to +60°C Storage Temperature: -40°~+85°C Equivalent Series Resistance: See table Shunt Capacitance (C0): 7pF maximum Load Capacitance (CL): Series or from 10pF to 32pF (Customer specified CL) Ageing: <±5ppm per year at +25°C Drive level: 0.5mW maximum Reflow Soldering: 10s maximum at 260°C twice or 180s at 230°C, once.
