Surface-Mount Feedthru Filters KYOCERA AVX Surface-Mount Feedthru Filters are an ideal way to reduce broadband EMI in a small SMD package. The filters can help reduce cost designs by eliminating some types of L/C filters, increasing system reliability, and saving PCB space. These filters are offered in 0805 and 1206 single-element packages or 1206 four-element packages. KYOCERA AVX Surface-Mount Feedthru Filters feature a unique construction of a feedthrough capacitor for low parallel inductance and an excellent decoupling capability for all high di/dt environments, and significant noise reduction in digital circuits.
