EURO QUARTZ MP4, MP5 CRYSTALS 12 x 4.5mm Compatible SMD Crystal 3.2MHz to 70MHz 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 MP4 and MP5 crystals provide clock signals (from 3.2MHz) in a lowprofile SMD package. The part is electrically and mechanically compatible with traditional industry SMD packages and may be used as a 'drop-in' replacement. USE WITH DOUBLE-SIDED PCBs MP4 and MP5 crystals are designed for top board assembly and one solder reflow process. Do not reflow this part with the can inverted.
