ECX-UM-1
SMD QUARTZ CRYSTAL
ECS offers all characteristics of the UM-1
with a metal jacket for surface mount
applications. This crystal has a very wide
frequency range from 3.6864MHz to 225MHz
for use in wireless communication applica-
tions requiring tight tolerance specifications
such as ± 5 PPM over -10˚C to +60˚C.
FEATURES
• 3.6864MHz to 225MHz frequency range
• Very small foot print for critical space applications
• Resistance weld enclosure
•
RoHS Compliant
• Tape & Reel (1,000 pcs)
