Filtered bulkhead connector.

Filtered bulkhead connector.

Filtered bulkhead connector.

I am going through a bulkhead using an L-C-L (T-section) feedthru filter, in other words the line goes in through an inductor, with a capacitor to the bulkhead, and an inductor on the way out. Clearly I am trying to get good filtering, but this is a signal line not a power line. The signal is only moving relatively slowly (<1MHz) but I want RF filtering at 10MHz and above. Using a feedthrough filter gives nasty exposed wires.

Is there such a thing as a feedthru with a shielded connector on the outside world? An SMA would be nice.

RE: Filtered bulkhead connector.

Ferrite bulkhead filters would work well in this frequency range.  There are connectors with them built in (such as D-Sub).
