EURO QUARTZ MP24, MP25 CRYSTALS 11.4 x 5.0mm SMD Crystal 3.2MHz to 70MHz FEATURES Frequency range 3.20MHz to 70.0MHZ Fully RoHS compliant Two height profiles available, 4.8 or 3.8mm Standard EIA tape and reel supply DESCRIPTION OUTLINE & DIMENSIONS MP24 and MP25 crystals provide 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. USE WITH DOUBLE-SIDED PCBs MP24 and MP25 crystals are designed for top board assembly and one solder reflow process. Do not reflow this part with the can inverted.
