FIELD: electronic equipment.
SUBSTANCE: invention relates to electrical engineering and electronics and can be used for suppression of high-frequency or pulsed interference in electric circuits. Interference filter comprises throttle consisting of toroidal ferromagnetic core with one or more windings, electrostatic screen in the form of toroidal metal shell of rectangular cross section with annular through slot, inside which there is a ferromagnetic core, at that windings of throttle are arranged on electrostatic screen, which is connected mechanically and electrically to the housing of the filter or protected device.
EFFECT: wider frequency range and increase of noise suppression.
