Dispositivo sensor de corriente de montaje superficial

摘要

The SMD current sensor device comprises: - a magnetic core; and - first (31) and second (43) windings respectively wound around first and second sections of the magnetic core. Most of first winding (31) is over moulded with an electrically insulating material defining a first envelope (3) defining a through hole (33) for the introduction therein of the first section of the magnetic core, and the device comprises an electrically insulating support (44) around which the second winding (43) is wound and which defines a through hole (42) for the introduction therein of the second section of the magnetic core, both through holes (33, 42) being aligned to each other. The uses of the SMD current sensor device are for sensing an excess of electrical current circulating through the first winding and for accurately measuring the magnitude of said electrical current.
