EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE 3.2 x 2.5 x 0.7mm SMD
DESCRIPTION
MT crystals are ultra-miniature AT-cut crystals covering the frequency range 12MHz to 60MHz in fundamental mode and up to 150MHz in 3rd overtone 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 Frequency Range 60MHz to 150MHz, 3rd overtone mode Ultra-small package 3.2mm x 2.5mm x 0.6mm Packaged in standard EIA tape and reel Ideal for PDAs, hand-held GPS, PCMCIA etc. OUTLINE & DIMENSIONS Frequency Range AT-Cut Fundamental: 12.0MHz to 60.0MHz AT-Cut 3rd Overtone: 60.0MHz to 150MHz Calibration Tolerance at 25ºC*: ±10ppm, ±20ppm, ±30ppm Frequency stability* -10° to +60°C from ±5ppm -20° to +70°C from ±10ppm -30° to +85°C from ±10ppm Storage Temperature: -40°~+85°C Equivalent Series Resistance: See table Shunt Capacitance (C0): 2pF to 4pF typical, 5pF maximum Load Capacitance (CL): Series or from 10pF to 32pF (12pF standard) Ageing: <±3ppm per year at +25°C Drive level: 100 microW maximum Reflow Soldering: 10s maximum at 260°C twice or 180s at 230°C, once. Packaging: 16mm EIA tape and reel SPECIFICATION 16.0000 12 MT-16000-12 30/50/-20+70/100R 16.3840 12 MT-16384-12 30/50/-20+70/100R 20.0000 12 MT-20000-12 30/50/-20+70/100R 20.5720 12 MT-20572-12 30/50/-20+70/50R 20.9450 12 MT-20945-12 30/50/-20+70/50R 24.5500 12 MT-24550-12 30/50/-20+70/50R 24.5760 12 MT-24576-12 30/50/-20+70/50R 29.4912 12 MT-29491-12 30/50/-20+70/50R 32.0000 12 MT-32000-12 30/50/-20+70/50R 32.7680 12 MT-32768-12 30/50/-20+70/50R 40.0000 12 MT-40000-12 30/50/-20+70/50R 48.0000 12 MT-48000-12 30/50/-20+70/50R 50.0000 12 MT-50000-12 30/50/-20+70/50R Frequency (MHz) CL (pF) Euroquartz Part Number STANDARD PART NUMBERS AND SPECIFICATIONS *Note: Tighter stability, tolerance and lower ESR values are available.
