  前言

  在当前产品小型化趋势下,电感尺寸不断缩小,以适配消费电子、汽车、快充及AI设备对轻薄化和高集成度的需求。同时,高磁导率、低损耗磁粉与高性能线圈材料的进步,使小尺寸器件能满足大电流和低损耗要求。

  核心工艺与结构

  采用粉末压注成型(PIM) 工艺,磁芯与线圈一体化成型,无传统组装间隙;全封闭磁屏蔽结构,抗EMI干扰强;尺寸为 0.8 mm(长)×0.4 mm(宽)~1.0 mm(长)×0.7 mm(宽),厚度多为超薄规格(常配套0.4~0.6 mm0.5~0.65mm),比传统绕线电感体积缩小30%+,是10–30g整机重量控制的关键方案。

  关键性能优势

  低损耗:DCR较行业均值低25%,1 MHz高频下磁损下降40%,显著降低电源系统功耗;实测可让AR眼镜续航提升约25%。

  高抗干扰与稳定性:辐射噪声比传统产品低30 dB;高饱和磁通密度,可承受瞬时大电流,适配端侧AI推理的动态功耗波动;机械强度高,耐振动冲击。

  典型应用场景

  主打AI/AR智能眼镜、微型传感器、蓝牙耳机、可穿戴医疗设备等高密度、超轻量、高频动态电流的场景;适配DC-DC降压/升压、电源管理单元(PMIC)、射频前端等模块。

  选型与定制提示

  1. 该规格属于定制化超微型号,标准料号需联系华萃微感确认;常见感量覆盖nH级至低μH级0.1μH~4.7μH(如0.1μH、0.22μH、0.47μH等),精度多为±20%;

  2. 饱和电流(Isat)、温升电流(Irms)、DCR值会随感量/厚度配置变化;

  3. 支持按PCB板厚、焊盘尺寸、电流/频率需求做专属规格定制。
