PIEZO FILTERS SURFACE MOUNTED CHIP PIEZOELECTRIC CERAMICS FILTERS FOR AM APPLICATIONS CFUCG, SFGCG, SFPC, CFWC 455kHz Along with the development of the AM chip filter, IF filters for AM 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.
