EURO
QUARTZ
12 x 4.5mm Compatible SMD Crystal
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
MP4 and MP5 crystals provide clock signals (from 3.2MHz) 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
MP4 and MP5 crystals are designed for top board assembly and one
solder reflow process. Do not reflow this part with the can inverted.
