Abstract

The invention relates to a surface-mounted transformer EER3515 soft magnetic ferrite core for LED displays. The core is in an E-shaped structure, 34.7-35.7mm in length, 12.15-12.85mm in width and 7.1-7.5mm in height. Compared with the prior art, the core which is a thin core can be applied to LED liquid crystal televisions so that the height of a PCB can be reduced and thin liquid crystal televisions can be produced; in addition, through the use of the core, production cost of transformers can be reduced, production efficiency can be improved, cost performance of LED televisions can be improved effectively, and market competitiveness is improved.

Description

technical field [0001] The invention relates to a soft ferrite core with high frequency, high Bs, low loss and high stability, in particular to an EER3515 soft ferrite core for surface mounting transformers for LED displays. Background technique [0002] In recent years, with the demands of consumers on the LCD TV industry, LCD TVs are developing in the direction of energy saving, light weight, and thinning. The price of iron core materials used in electronic transformers in displays continues to rise, and upstream raw materials form a seller's market. As the power users of downstream electronic transformers, they can choose and purchase on a global scale, forming a buyer's market. The electronic transformer industry, which is in the middle, can only get rid of this kind of dilemma by taking the road of technological innovation. However, in the mature electronic transformer industry, technological innovation is more difficult. But the improvement of every small link can br...
