A standing wave filter prevents a cable acting as a transmission antenna. The unwanted effect is often that as a computer interferes with reception of radio or television. This antenna effect is reduced with ferrite cores. Ferrite Core - sheath current filter (English: common- mode choke ) consist of a ferrite sleeve which includes a conduit or cable bundles. It is current-compensated chokes. Try attenuating high-frequency Gleichtaktstörsignale on lines.

Frequently standing wave filters are mistakenly equated with ferritfilters.

They act against high-frequency common-mode currents in excess of about 50 MHz and will not affect the signal and the ground connection in terms of their low-frequency properties, or protection. Ferrite Core - sheath current filter can not effectively attenuate ground loop hum.

Cables for connection of computer peripherals often have a Ferritkerndrossel. The line can also be performed several times to increase the inductance by a ferrite core.

Ferrite Core - sheath current filter can only work efficiently if a Gleichtaktstörstrom flows on a line. Which is generally the case if a trunk group or a coaxial line at both sides having a mass connected to the grounded equipment.

For a trunk group between two devices, of which only one unit is grounded, a ferrite core - sheath current filter does not work in general. In such a ground to standing waves would formation, possibly as standing waves. For standing waves ferrite core ferrits act only at the places where. Depending on frequency and wavelength, a current stomach, but not where to set a current node

Ferrite Core - sheath current filter are available for different frequency ranges and current carrying capacity.
