ECS-SR-B SERIES SMD CERAMIC RESONATOR
The ECS-SR-B Series SMD ceramic resonator
FEATURES
includes built in capacitors for simplification
of oscillator circuits and reduces component
count. The SMD ceramic resonator is an
excellent low cost frequency control solution
when absolute frequency accuracy is not
important.
•
Low profile SMD package
• Wide frequency range
• Built-in load capacitor
• Tape & Reel packaging
