Abstract
The utility model discloses an XY capacitor, comprising a shell which is internally provided with two metal electrodes; an insulated medium is arranged between the two metal electrodes; the shell is an electromagnetic shielding shell; alternatively, an electromagnetic shielding layer is arranged outside the shell. The XY capacitor has electromagnetic interference resistance and simple structure.
Description
Technical field
The utility model relates to a kind of electric capacity, relates in particular to a kind of XY electric capacity.
Background technology
The development of power technology and power supply user's demand all causes power density to increase, and the thing followed is exactly that the electromagnetic field intensity of power module inside is increasing, and finite volume, so it is serious day by day to cause marching into the arena of inside modules electromagnetic field to be disturbed.The Primary Component that suppresses EMI can adopt XY capacitor element, and wherein, X electric capacity is often referred to the electric capacity that is connected between L, N (L, the L) line, also comprises the electric capacity between the positive negative wire; Y electric capacity is often referred to the electric capacity that is connected between L, N line and the PE, also comprises the electric capacity between positive negative wire and the PE; X, Y electric capacity include but not limited to XY safety electric capacity, these XY capacitor elements also are easy to disturbed, because electric capacity is to use as the Primary Component of filter in product, if they are disturbed, to directly cause filter by short circuit, ineffective, can cause EMI (EMC) test result to worsen, influence test result.
The utility model content
The technical problems to be solved in the utility model provides a kind of anti-electromagnetic interference, XY electric capacity simple in structure.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of XY electric capacity, comprise shell, be provided with two metal electrodes in the shell, be provided with dielectric between the metal electrode, described shell is shielding casing or at the shell peripheral hardware electro-magnetic screen layer is arranged.
Described shielding casing is metal shell, high-permeability material shell or conductive plastics shell.
Described high-permeability material shell is dilval shell, sloping Mo alloy shell or si fe alloy shell.
Described conductive plastics shell is structural conductive plastic casing or composite conductive plastic shell.
