Summary of the invention

This utility model is for the problems referred to above, it is provided that a kind of common-mode filter pad compatibility PCB that can save pcb board space Plate.

Described common-mode filter pad compatibility pcb board, including body, body includes match with common-mode filter pin Two pads that four pads and the first resistance pins match and two pads matched with the second resistance, common mode filtering The pad that on pad that on device, the first pin matches and the first resistance, the first pin is mated coincides, on common-mode filter the 4th The pad that on pad that pin matches and the first resistance, the second pin is mated coincides, and on common-mode filter, the second pin is mutually The pad that on the pad joined and the second resistance, the first pin is mated coincides, the pad that on common-mode filter, the 3rd pin matches The pad mated with the second pin on the second resistance coincides.

Further, described common-mode filter, the first resistance, the second resistance are according to the welding of pin pad coincidence corresponding relation admittedly Fixed.

Specifically, the common-mode filter that during described common-mode filter is Mobile phone PCB, LCDs is corresponding.

Specifically, the common-mode filter that during described common-mode filter is Mobile phone PCB, photographic head is corresponding.

Common-mode filter pad compatibility pcb board described in the utility model, is designed by the coincidence of respective pad, it would be desirable to connect Common-mode filter and resistance corresponding pin jointly weld together, with reach connect respective pins purpose, compared to existing cloth In line design, need first to be respectively welded to pin mate on pad, then the pad corresponding to the pin connected will be needed by printing Guide the mode being connected and there is saving pcb board space, facilitate cabling, be conducive to adding circuit layout corresponding to what's new Advantage.
