QUARTZ
13.1 x 9.4mm SMD
Frequency range 3.5MHz to 70.0MHZ
Fully RoHS compliant
Industry-standard package
Standard EIA tape and reel supply
DESCRIPTION
86SMX crystals were among the first surface mount crystal designs
available in the industry. As a result the package is still widely used.
Supply on 24mm EIA tape and reel is standard.
