EURO QUARTZ · · · · MP CRYSTALS 12mm x 4.5mm SMD Low frequencies from 3.5MHz to 70.0MHZ Fully RoHS compliant Two height profiles available, 4.8 or 3.8mm Standard EIA tape and reel supply DESCRIPTION OUTLINE & DIMENSIONS The MP crystal provides an ideal source of low frequency clock signals (from 3.5MHz) in a low-profile SMD package. The part is electrically and mechanically compatible with traditional industry SMD packages and may be used as a 'drop-in' replacement.
