    Hi guys,

    Just a quick one - how do you properly pass a signal wire through a shield? I've heard of feed through capacitors but upon reading more, these don't seem like quite the right component.

    Cheers,

    Dan

    several kinds of feedthrous are made, from just insulated streight through to built in inductance and shunt capacitance for blocking rf.

    This is really old news, but in 1970, a feed thru capacitor meant a solid wire going through the metal case and it has capacitance to the case intentionally calibrated, usually in the neighborhood of 10 pf. What? They don't make those any more?

    What is the nature of the signal?

    The signal is simply a 300kHz sine. I want to pass it through a faraday cage shield such that the shield and signal wire have no interaction with each other whatsoever
