EURO QUARTZ
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.
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.
