MARUWA GENERAL CATALOG
SCREW TYPE EMI FILTERS [ FTA Series ]
The FTA series are extremely small, highly reliable EMI filters for a wide range of frequency, and are suited for high
frequency noise and EMI control.
For this series, a feed through type ceramic capacitor with
an extremely high self-resonating frequency is soldered into
a threaded metal shell, and sealed with resin.
