DK 型磁心
DK Magnetic Cores
品质简述：
·为适应通讯技术，特别是双向传输技术和卫星通讯技术的发展，射频宽带铁氧体材料在宽频带范围内（5～1000MHZ、5～2500MHZ）完成阻抗变换、阻抗匹配和功率传输等功能；可作各种电感器的调节磁心及高频扼流圈和固定电感器磁心。
·抗EMI铁氧体材料在抗EMI材料中不失为高效廉价的材料，尤其在电子设备向高频化方向发展中，它的作用更加突出。抗EMI铁氧体材料制成的磁心套在电源线、信号线上以降低电磁噪声、尖峰脉冲、浪涌和静电放电的干扰，使电子设备符合电磁兼容（EMC）和静电放电（ESD）相应的技术要求。
·频带范围宽、低插损、高隔离、高反射损耗。
