Abstract

The invention relates to a surface adhered type magnetic device. The surface adhered type magnetic device comprises a first magnetic core and a second magnetic core. The first magnetic core comprises a first end portion, a second end portion, a middle column and multiple coils, wherein the bottom of the first end portion and the bottom of the second end portion are respectively provided with a plurality of outer electrodes, the multiple coils are wound on the middle column, and two ends of each coil are connected with two outer electrodes of the first end portion or two outer electrodes of the second end portion. The second magnetic core is arranged at the top of the first magnetic core to form a closed magnetic circuit.

Description

technical field [0001] The invention relates to electronic components, in particular to a surface-mounted magnetic device. Background technique [0002] With the development of electronic technology, electronic components are gradually developing toward surface mount, miniaturization, and high reliability, and products are required to be able to adapt to high-speed dense mounting. Digital subscriber line (Digital Subscriber Line, DSL) equipment uses a large number of magnetic devices for isolation and signal conversion. With the continuous advancement of semiconductor technology, the chip integration level continues to increase, but the level of automation in processing magnetic devices is low, and the small size of magnetic devices The pace of digitalization significantly lags behind the pace of improvement in chip integration, which restricts the development of high-density and miniaturized DSL equipment. [0003] At present, the magnetic cores of the magnetic devices use...
