The screw type EMI filter FT series has a T or circuit structure according to the combination with multilayer suppressors in a threaded metal shell, using multilayer feed through type ceramic capacitors and extremely small feed through type ceramic capacitors.
It offers extremely large insertion loss in a high frequency range up to microwaves, and performs filtering and shielding concurrently for electronic equipment. |

■Features
| • |
Since a feed-through lead wire as a current channel has no internal connection, the EMI filters achieve large allowable current, and can be used for DC lines from 15A(Φ1.0) to 5A(Φ0.65). |
| • |
RoHS Compliant. |
|
|
■Applications
EMI measures for DC lines and signal lines of base station for cellular phone, microwave transmission, and test equipment. |
