12 x 4.5mm Compatible SMD Crystal
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.
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
