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
MP CRYSTALS
12mm x 4.5mm SMD
DESCRIPTION
The MP crystal provides 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.
