【元件】 全磁屏蔽工艺进一步提升EMC特性!适用于可穿戴设备的顺络高性能MWPU系列绕线功率电感
产品图片
概要
顺络全磁屏蔽、小型化设计MWPU系列绕线功率电感已实现量产。MWPU系列选用高磁导率、高Bs、低损耗材料,同时搭配精密绕线和全磁屏蔽涂覆工艺,实现小型化、高饱和电流、高抗干扰能力。尺寸范围覆盖1.0x0.5(mm)~1.6x0.8(mm),广范应用于智能穿戴设备、小型便携式医疗设备等。
背景和开发目的
目前,由于空间限制和强磁场的影响,TWS耳机、手表等智能穿戴设备越来越关注磁场干扰问题。为了增加电感的抗EMI能力及降低对周边器件的磁场干扰,顺络采用二次点胶涂覆工艺,开发了一款全磁屏蔽绕线片式电感MWPU系列,进一步提升产品的EMC特性。

产品优势
精密绕线,全磁屏蔽工艺
MWPU系列增加二次点胶工艺,将线圈全包覆,避免了磁力线外泄风险,进一步提升EMC特性。
高Bs、低损耗磁芯材料,提升可穿戴设备电池续航能力
对于TWS耳机等智能穿戴设备,除了底噪和小型化,电池续航能力也是一直以来备受厂家关注。因此,在满足小型化同时,顺络MWPU系列进一步优化磁芯材料,采用高Bs、低损耗合金材料,提高产品通流能力,并降低DCR和ACR,从而降低产品损耗,提升电池续航能力。
对比MWPH系列,拥有更高的饱和电流
相同的尺寸和感量下,以尺寸1608,感量2.2/4.7/10μH为例,MWPU系列饱和电流相较于MWPH系列提高了12%以上,且MWPU1608A合金系列饱和电流高出2倍以上。
