QUARTZ
11.4 x 5.0mm SMD Crystal
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.
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
