The EM-7858 10 µf feed-through capacitor provides a path of low RF impedance across a power source so that EMI currents produced by the equipment under test can be accurately measured with a current probe.

It is used for EMI testing to SAE, MIL-STD-461/462, plus numerous other government and commercial specifications and requirements.

The capacitor can also be used as a power line filter if installed in the wall of a shielded enclosure.

The EM-7858 will easily accommodate power currents in excess of 100 amperes without voltage loss or excessive heating.
