SMD CERAMIC RESONATORS SMD CERAMIC RESONATORS
The ECS-SR-B Series SMD ceramic resonator
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.
