最大能够承载6A电流的2220封装高品质磁珠
LAIRD公司出品的电磁屏蔽产品在全世界处于领先地位,占据全球前3的位置,产品种类齐全,采用一流的质量管理,其推出的磁珠质量优异,值得客户信赖。本文为客户介绍其推出的2220大封装磁珠产品HI2220系列,该系列产品能够通过大电流,是电源接口和功率电路中滤除高频噪声和干扰的最佳选择,其可选型号有HI2220P171R-10,HI2220P251R-10,HI2220P271R-10,HI2220P551R-10,HI2220P601R-10,HI2220P701R-10,HI2220Q401R-10,HI2220R151R-10,HI2220R181R-10,HI2220R301R-10,HI2220T101R-10等。
查询这几款通流能力大的磁珠可以发现,其最大通流能力能够做到6A,这与其采用了2220封装有着很大关系,在较大封装能放置更多的铁氧体材料,故而能承载更大电流。这种通流能力已满足绝大多数非大功率卡件的供电要求,因此可以用在电源接口和小功率电路中。
对于磁珠而言,由于在高频时呈现阻性,因此在Laird的手册中提供的是磁珠的频率阻抗曲线,用户根据自己的频率需求选择合适的磁珠,以HI2220P171R-10为例,由图1可知随频率增加,阻抗增大,在500MHz附近达到峰值,处理此频率附近的干扰信号最佳,典型阻抗值为170Ω。但是值得注意的是,随着使用电流的增加,中心频点会向右移动,并且峰值会降低,因此需要结合实际电流大小进行选型。
图1 HI2220P171R-10频率-阻抗图
对比不同磁珠,会发现一个特点,阻抗大的允许通过的电流小,阻抗小的允许通过的电流大,这样典型的例子通过对比HI2220P701R-10和HI2220T101R-10可以发现,这也是由于封装和工艺的原因造成的,因为同样的体积内同种材料制作的磁珠在通流的情况下能够承载的功率是有限的,故而出现这样的情况。用户在选型时一定要根据需求的抑制效果和通流能力相匹配,做出合理选型。

【选型】饱和电流高达5A的铁氧体磁珠HI0805R800R-10助力手持电动工具EMI设计,DCR低至0.01Ω
手持电动工具内部包含电机、MOS、DCDC等器件,在工作中会产生高频噪声导致EMI干扰。最简单的解决方案是用磁珠来抑制高频噪声,推荐Laird的磁珠HI0805R800R-10,典型高频阻抗80Ω@100MHz,是手持电动工具EMI设计的优秀解决方案。
【应用】可覆盖300Hz至2GHz频段范围的铁氧体磁珠,为消除高频噪声和尖峰干扰中提供解决方案
磁珠的主要由铁氧体材料组成,铁氧体通常可以等效为电阻和电感并联,在低频时电阻被电感短路,高频时电感阻抗较大,以至于电流全部通过电阻从而把交流电流转化为热能,而磁珠的主要应用是消除存在于电路板中的射频噪声。Laird公司推出了各种应用场景的产品,例如适合圆线缆的实心铁氧体磁芯、抑制高频共模和差模信号的可拆卸的塑料壳铁氧体磁芯等一系列产品。
保护电子产品的高性能材料
描述- Laird Performance Materials,现为杜邦公司的一部分,专注于为电子设备提供高性能材料,以保护电子元件并确保信号完整性和功率传输。公司提供包括EMI吸收材料、热管理材料、结构金属和多功能产品在内的多种解决方案,旨在帮助客户实现更高的性能、可靠性和更快的上市时间。Laird的产品广泛应用于汽车、医疗设备、数据基础设施、可穿戴设备、游戏和娱乐设备等领域。
【应用】最大通流4A的大功率磁珠HI2220P601R-10可用于77GHz汽车毫米波雷达电源,提供输入端高频滤波功能
77GHz汽车毫米波雷达方案核心器件是微波收发芯片,通常集成射频收发和处理器功能,电源部分通常采用DCDC降压转换器,外部电源是采用车载供电,高频杂波和干扰比较大,因此为了降低杂波对DCDC转换器的影响,电源输入端需要磁珠来完成高频滤波功能,推荐Laird的大功率磁珠HI2220P601R-10,通流能力4A,典型阻抗600欧姆,封装2220,适用于汽车雷达电源接口滤波应用。
