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
