PIEZO FILTERS
SURFACE MOUNTED CHIP PIEZOELECTRIC CERAMICS FILTERS
FOR AM AND FM APPLICATIONS
SFECV 10.7MHz, SFECS 10.7MHz
Along with the development of the AM chip filter, IF filters for
AM/FM radios have also been made smaller, thinner and in
a chip configuration for surface mounting. This is one more
example of Murata Electronics’ leadership in converting
conventional electronic components to chip technology.
