Würth Elektronik WE-CBA SMD EMI抑制铁氧体磁珠

Wurth Electronics WE-CBA SMD EMI抑制铁氧体磁珠符合AEC-Q200标准,可直接放在印刷电路板上。这些铁氧体磁珠具有出色的抗电磁干扰性能和低直流电阻。当靠近干扰源放置时,即使是具有0402最小尺寸的器件,也能达到1000Ω的最大阻抗。Wurth Electronics WE-CBA系列铁氧体磁珠非常适合用作为配电电压解耦的数据滤波器。其他应用包括USB 2.0、控制信号、RS232、RS422、直流/直流转换器和电源。

元件

  • High-speed SMD ferrites have a lower impedance in the lower frequency ranges, giving them a low attenuation for fast signals. Applications include USB 2.0, IEEE 1394, and LVDS.
  • Wide-band SMD ferrites (WE-CBF) show high impedance in the low-frequency range, making them wide-band through the whole spectrum. Applications are control signals, RS232, RS422, and DC/DC converters.
  • High-current SMD ferrites are designed for high currents over 1A. The rated current refers to 40K self-heating. High-current SMD ferrites are available in all three types (high speed, wide band, and high frequency). Applications include power supplies and DC/DC converters.

特性

  • 可靠的Ni-Sn电极
  • 额定电流高达5A
  • 工作温度:-55°C至+125°C
