EURO
QUARTZ
11.4 x 5.0mm SMD Crystal
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
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.
MP24, MP25 CRYSTALS
3.2MHz to 70MHz
OUTLINE & DIMENSIONS
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.
