摘要： A common mode choke may include a generally rectangular body including bottom and top ferrite portions, at least one pair of laterally spaced apart interior conductors between the bottom and top ferrite portions and extending between the first and second ends of the generally rectangular body, and a dielectric material layer between the bottom and top ferrite portions. Moreover, the dielectric material layer may also extend laterally between the at least one pair of interior conductors and may also at least partially encapsulate the at least one pair of interior conductors at portions thereof opposite at least one of the bottom and top ferrite portions. The choke may also include end conductors on the opposite ends of the generally rectangular body and connected to the interior conductors. A compact footprint is provided for the common mode choke while maintaining a high level of electrical performance.

摘要： A filter device may include a plurality of ferrite filters laminated together in vertically stacked relation, where each ferrite filter may include a pair of ferrite layers laminated together in vertically stacked relation and a lateral conductor extending therebetween. The filter device may also include at least one vertical conductor connecting the lateral conductors together in series. Moreover, at least some of the ferrite filters may have different operating characteristics. In particular, the different operating characteristics may be different impedance versus frequency characteristics to thereby broaden an attenuation frequency band of the filter device.

摘要： An inductor, such as for electromagnetic interference (EMI) suppression, comprises a plurality of ferrite layers arranged in stacked relation and joined together to define a ferrite body, and a first electrical conductor extending between a first pair of adjacent ferrite layers. The inductor includes first respective opposing portions of the first pair of adjacent ferrite layers being sintered together, and second respective opposing portions of the first pair of adjacent ferrite layers being in spaced apart relation to define at least one first gap therebetween. Moreover, the device includes a sintering blocking material associated with the at least one first gap. The sintering blocking material causes the gap to form in the ferrite body to selectively block the magnetic path to thereby retain a higher inductance than would otherwise be possible at relatively high currents. In a surface mounting embodiment of the inductor, the ferrite body has a generally rectangular shape. In addition, a pair of end conductors are provided on opposing ends of the ferrite body to facilitate surface mounting of the inductor. The sintering blocking material may comprise a non-magnetic material. In particular, the sintering blocking material may comprise titanium-dioxide.
摘要翻译：诸如用于电磁干扰（EMI）抑制的电感器包括以层叠关系布置并连接在一起以限定铁氧体本体的多个铁氧体层，以及在第一对相邻的铁氧体层之间延伸的第一电导体。所述电感器包括所述第一对相邻铁氧体层的第一相对的相对部分被烧结在一起，并且所述第一对相邻铁氧体层的第二对应部分间隔开，以在其间限定至少一个第一间隙。此外，该装置包括与至少一个第一间隙相关联的烧结阻挡材料。烧结阻挡材料在铁氧体中形成间隙以选择性地阻挡磁路，从而保持比在较高电流下可能的电感更高的电感。在电感器的表面安装实施例中，铁氧体主体具有大致矩形形状。此外，一对端部导体设置在铁氧体的相对端部，以便于电感器的表面安装。烧结阻挡材料可以包括非磁性材料。特别地，烧结阻挡材料可以包括二氧化钛。

摘要： A common mode choke includes a plurality of joined together ferrite layers defining a generally rectangular body and comprising a bottom ferrite layer, a top ferrite layer, and at least one intermediate ferrite layer. The at least one intermediate ferrite layer preferably has an opening therein defining a cavity in the generally rectangular body extending from adjacent a first end thereof to adjacent a second end thereof. The choke also preferably includes at least one first pair of interior conductors extending on the at least one intermediate ferrite layer on opposite sides of the cavity. The choke may also include first and second pairs of end conductors on the first and second ends of the body that are connected to the interior conductors. The interior conductors may also have respective side edge portions exposed to the cavity in the body. In one embodiment, the opening in the at least one intermediate ferrite layer extends completely from the first end to the second end of the generally rectangular body. Air or another non-magnetic dielectric material may fill the cavity.
