  • Publication number: 20190096561
    Abstract: In a stepwise structure formed in a multilayer coil component, a difference occurs in a shrinkage amount between a maximum film thickness portion in which the number of layers is large and a minimum film thickness portion in which the number of layers is small due to portions different in the number of layers of coil parts (that is, upper coil part, lower coil part, and connecting part) adjacent to each other like the maximum film thickness portion and the minimum film thickness portion, readily causing a crack by an inner stress due to the difference in the shrinkage amount. In a multilayer coil component according to the present disclosure, a stress relaxation part overlapping with a maximum film thickness portion whose shrinkage amount is large is provided to relax inner stress in a stepwise structure, resulting in prevention of a crack.

  • Publication number: 20180233262
    Abstract: In a multilayer coil component, an end of a lower coil layer and an end of a connecting part are directly overlapped, and the end of the lower coil layer includes a contact edge positioned on a side of the connecting part and being in contact with the connecting part and a non-contact edge positioned on a side opposite to the connecting part and not being in contact with the connecting part. Then, the contact edge and the non-contact edge are not overlapped when viewed from a laminated direction. Consequently, a propagation distance of a crack becomes longer as compared with the case where an end face is parallel to the laminated direction, effectively suppressing advance of the crack. Suppressed advance of a crack in this manner makes the multilayer coil component provide a high component strength as a whole.
