W2H AEC-Q200 High Current Feedthru Capacitors KYOCERA W2H AEC-Q200 High Current Feedthru Capacitors are designed as broadband EMI filters that provide high current handling capability. These SMT feedthru filters offer an optimized frequency response with high attenuation across a wide RF spectrum due to optimized parallel and series inductances. The KYOCERA AVX W2H filters can replace discrete L/C filter networks and are automotive qualified.
