Abstract
Official abstract text for this publication.
A multilayer coil component including: a magnetic part that contains Fe, Zn, V, and Ni and optionally contains Mn and/or Cu; and a conductor part that contains copper. In the magnetic part, Fe is in an amount of 34.0 to 48.5 mol % expressed as Fe 2 O 3 equivalent, Zn is in an amount of 6.0 to 45.0 mol % expressed as ZnO equivalent, Mn is in an amount of 0 to 7.5 mol % expressed as Mn 2 O 3 equivalent, Cu is in an amount of 0 to 5.0 mol % expressed as CuO equivalent, and V is in an amount of 0.5 to 5.0 mol % expressed as V 2 O 5 equivalent, with respect to the total amount of Fe expressed as Fe 2 O 3 equivalent, Zn expressed as ZnO equivalent, V expressed as V 2 O 5 equivalent, and Ni expressed as NiO equivalent, and optionally present Cu expressed as CuO equivalent and optionally present Mn expressed as Mn 2 O 3 equivalent.
First claim
Opening claim text (preview).
1 . A multilayer coil component comprising: a magnetic part that contains Fe, Zn, V, and Ni and optionally contains Mn and/or Cu; and a conductor part that contains copper and that is in the form of a coil, wherein, in the magnetic part, Fe is contained in an amount of 34.0 to 48.5 mol % expressed as Fe 2 O 3 equivalent, Zn is contained in an amount of 6.0 to 45.0 mol % expressed as ZnO equivalent, Mn is contained in an amount of 0 to 7.5 mol % expressed as Mn 2 O 3 equivalent, Cu is contained in an amount of 0 to 5.0 mol % expressed as CuO equivalent, and V is contained in an amount of 0.5 to 5.0 mol % expressed as V 2 O 5 equivalent, with respect to a total amount of Fe expressed as Fe 2 O 3 equivalent, Zn expressed as ZnO equivalent, V expressed as V 2 O 5 equivalent, and Ni expressed as NiO equivalent, and optionally present Cu expressed as CuO equivalent and optionally present Mn expressed as Mn 2 O 3 equivalent. 2 . The multilayer coil component according to claim 1 , wherein the amount of Mn expressed as Mn 2 O 3 equivalent is 0.1 to 7.5 mol %. 3 . The multilayer coil component according to claim 1 , wherein the amount of Cu expressed as CuO equivalent is 0.1 to 5.0 mol %.
