  • Publication number: 20210304942
    Abstract: An object of the present disclosure is to provide a common mode noise filter that can be used in a high-frequency band. The common mode noise filter of the present disclosure includes first to fifth insulator layers and stacked body in which first to fifth insulator layers are stacked along a vertical direction. The common mode noise filter further includes first spiral conductor and second spiral conductor that are formed inside stacked body and face each other across first insulator layer. The common mode noise filter further includes first pad connected to an inner end of first spiral conductor and second pad connected to an inner end of second spiral conductor. Neither first pad nor second pad overlaps each of first spiral conductor and second spiral conductor in top view.

  • Patent number: 10937584
    Abstract: A common mode noise filter includes a non-magnetic body and first to third coil conductors provided inside the non-magnetic body. The second coil conductor is provided in a downward direction from the first coil conductor. The third coil conductor is provided in the downward direction from the second coil conductor. The first and third coil conductors deviate in a direction perpendicular to the downward direction with respect to the second coil conductor. At least one of the first and third coil conductors overlaps the second coil conductor viewing from the direction perpendicular to the downward direction. This common mode noise filter allows these coil conductors to be magnetically coupled to each other with a preferable balance, thereby preventing degradation of differential signals.

  • Publication number: 20210028752
    Abstract: The present disclosure provides a common mode noise filter that can improve attenuation characteristics of common mode noise over a wide frequency range. The common mode noise filter of the present disclosure includes: two magnetic sections and each of which is made of a magnetic material; and non-magnetic section disposed between magnetic sections in a stacking direction, non-magnetic section being made of a non-magnetic material. Moreover, the common mode noise filter further includes two coils and metal layer. Coils are disposed inside non-magnetic section while facing each other. Metal layer is formed inside at least one of two magnetic sections while being connected to the ground. Metal layers are positioned closer to a lower surface of magnetic section than an upper surface of magnetic section and closer to an upper surface of magnetic section than a lower surface of magnetic section.

  • Publication number: 20200303108
    Abstract: A common mode noise filter includes an insulating layer, a first coil conductor disposed on a first surface of the insulating layer and extending slenderly, and a second coil conductor disposed on a second surface of the insulating layer and extending slenderly. The second coil conductor faces the first coil conductor across the insulating layer. A portion of the second coil conductor has a cross section crossing a direction in which the portion of the second coil conductor extends slenderly. The cross section includes an apex portion facing the first coil conductor across the insulating layer and a base side portion opposite to the apex portion. A width of the apex portion is smaller than a width of the base-side portion. The common mode noise filter reduces attenuation of differential signals in high frequencies.

  • Patent number: 4588595
    Abstract: A culture containing a viable mass of Bifodobacteria and lactic acid bacteria is obtained by incubating separately or together microorganisms of the genus Bifidobacterium and Lactobacillus, and the species Streptococcus thermophilus in a medium containing milk as the main ingredient. The Streptococcus thermophilus is a strain having high oxygen uptake. When incubated separately, the microorganisms are mixed together after incubating. In the presence of the high oxygen uptake Streptococcus thermophilus, a high survival fraction of the Bifidobacteria is obtained when the culture is stored under aerobic conditions. The culture is useful in preparing food, medicine or feed.
