FTT Series

FTT Series


These are feed through EMI filters with T type circuit structure, containing a feed through ceramic capacitor with an extremely high self resonating frequency and ferrite beads. Therefore, the filters can efficiently suppress EMI over a wide range band up to GHz without a significant decrease of insertion loss which causes by coaxial resonance. Also, they have high reliability with resin-sealing that has high resistance against humidity and thermal resistance.
