Product description

MT crystals are ultra-miniature AT-cut crystals covering the frequency range 12MHz to 60MHz in fundamental mode. Their small size and low mass makes these crystals ideal for miniaturized hand-held equipment and similar high-density applications.

Product features

  • Frequency range 12MHz to 60MHz, fundamental mode
  • Ultra-small package 3.2mm x 2.5mm x 0.6mm
  • Entire package may be grounded via metal lid and two pads
  • Packaged in standard EIA tape and reel
  • Extremely low ageing with high shock and vibration resistance
  • Ideal for PDAs, hand-held GPS, PCMCIA etc
