FIELD: radio electronics.
SUBSTANCE: invention relates to radio electronics and can be used in means of miniaturization of electronics to limit the level of conducted emissions and protect radio-electronic equipment (REQ) from short and ultra-short duration impulse noise propagating through power supply circuits. To achieve the effect, at one end, the active conductors of the strip structure are connected in series to the input terminals for connecting a protective device into the break of a 2-wire network line, at the other end, the active conductors are connected in series with the input contacts of a common-mode choke having two inductively coupled windings on a common toroidal ferromagnetic core connected in parallel to each other, but in series with respect to the strip structure.
EFFECT: invention increases the attenuation of ultrashort pulses (USPs).
