Automotive Noise / EMI Suppression Filters

Murata Electronics Automotive Noise / EMI Suppression Filters offer components for noise suppression from various approaches, such as small-sized EMI suppression filters and AC line filters that effectively suppress noise. Also among these components are ferrite cores and microwave absorbers, which suppress noise even after the set is completed. Murata offers ESD protection devices that protect semiconductors from static electricity entering from outside.
