ECX-64A/64C
SMD QUARTZ CRYSTAL
The ECX-64A and ECX-64C are subminature
SMD crystals with 3.5 X 6 mm footprint. This
cost effective all ceramic package is available
in 2 and 4 pad versions. The package height
measures 1.1 mm max. which is ideal for
densely populated PCB applications.
FEATURES
• Compact and low profile
• Glass sealed ceramic package
• RoHS Compliant (Note 7 exemption for Pb)
