楼氏电容推出表贴式EMI滤波器,额定电压为25Vdc至200Vdc,是航空航天等高可靠性应用的绝佳选择
当前,许多电子元件制造商选择大批量生产满足消费类电子应用的产品,之后随着专业元件生产设备的老化,会逐步淘汰该类产品的生产——表贴式抗电磁干扰(EMI)滤波器即是其中的一种。这类三端子滤波器基于传统的多层陶瓷电容(MLCC)制造技术,在端头与端头间形成一个较短的电路,各端头间(含两端及侧面/接地)形成电容。
凭借这样的结构,过滤后的信号通过芯片的内部电极,噪声被过滤到接地侧的触点,从而缩短了噪声传输路径的长度。与传统的两端头MLCC元件相比,由于线和地之间的内部电感减少了,衰减得到了改善。因此,这类滤波器提供的滤波性能大大超过许多应用的要求,是航空航天和国防领域高可靠性应用的绝佳选择。
作为电容器、滤波器等精密电子器件的专业制造商,楼氏电容(KNOWLES)不仅致力于表贴式EMI滤波器的生产制造,而且还在该领域持续投资,不断推出创新产品。目前,楼氏电容有三种型号的表贴式EMI滤波器可供选择01,E07,E17系列——最大额定电流为300mA,2A和10A,额定电压为25Vdc至200Vdc,采用C0G/NP0和X7R电介质。楼氏电容还在致力拓展更高的电流可选项以及更宽泛的电流范围。以下表格详细介绍了该系列产品的最新规格。
楼氏电容的X7R EMI滤波器也可使用FlexiCap™柔性端头(图1)。FlexiCap™是楼氏电容专有的柔性环氧聚合物端头材料,位于通常的镍阻挡层之下,与普通端头材料相比,具有更高的可靠性和卓越的机械性能。针对汽车电子应用,楼氏电容也可提供符合AEC-Q200要求的车规品。

【经验】CAN FD如何选用滤波器?
CAN FD选用滤波器要求:1、CAN FD的共模滤波器要求更高的速率;2、CAN FD的共模滤波器对差共模转换要求更高;3、需要更高的共模阻抗来抑制干扰;4、为了抑制谐振产生,共模滤波器需要自身寄生电容要小。
【元件】聚焦高端MLCC,微容科技推出“千伏级高压与高容高温“车规MLCC
微容科技近期将携多款明星新品亮相,其中包括全球行业领先的极限规格1206、1210等大尺寸车规MLCC:高压系列中电压可达630V-1000V,适用于车载三电系统中;400V/800V平台多合一电源、电驱电控高压电气系统等;典型规格如:1206 C0G 10nF 630V; 1210 C0G 15nF 1000V;1210 C0G 22nF 1000V ; 1210 C0G 33nF 630V 。
【经验】解析SLC和MLCC这两种电容器的应用
在电路设计初期,工程师们就需要决定是选用单层电容器(SLC)还是多层陶瓷电容器(MLCC)来满足应用需求。今天Knowles(楼氏)和你分享如下:总的来说,两者似乎有类似的功用,因为无论是SLC还是MLCC,它们都可作电路中的充储电、滤波或旁路之用。
解析缓冲电容器的实际应用
鉴于缓冲电容器可解决开关带来的负面影响,因此在开关电源中最常见到缓冲电容器也就不足为奇了。这些系统面临着开关带来的重大挑战,包括开关瞬态 、寄生元件 、高频噪声等。本文介绍缓冲电容器的实际应用。
