Claims
- 1. A permeable magnetic composition, comprising 5-30 wt. parts of polyarylene sulfide resin and 70-95 wt. parts of Ni-Zn-Cu-based ferrite powder providing a total of 100 wt. parts together with the polyarylene sulfide resin, said Ni-Zn-Cu-based ferrite having a composition represented by the following formula (1):
- Ni.sub.a Zn.sub.b Cu.sub.c Fe.sub.2 O.sub.d,
- wherein a, b, c and d are numbers satisfying 0.10.ltoreq.a .ltoreq.0.70, 0.10.ltoreq.b.ltoreq.0.80, 0.10.ltoreq.c.ltoreq.0.35 and 3.97.ltoreq.d .ltoreq.4.20.
- 2. A composition according to claim 1, wherein the numbers a-d satisfy 0.15.ltoreq.a.ltoreq.0.50, 0.40.ltoreq.b.ltoreq.0.75, 0.15.ltoreq.c.ltoreq.0.30, and 3.98.ltoreq.d.ltoreq.4.15.
- 3. A composition according to claim 1, comprising 7-25 wt. parts of the polyarylene sulfide resin and 75-93 wt. parts of the Ni-Zn-Cu-ferrite powder.
- 4. A composition according to claim 1, further containing 0.1-5 wt. % of epoxidized silicone oil.
- 5. A magnetic component, comprising a molded product of a permeable magnetic composition according to claim 1.
- 6. A magnetic component, comprising a molded product of a permeable magnetic composition according to claim 2.
- 7. A magnetic component, comprising a molded product of a permeable magnetic composition according to claim 3.
- 8. A magnetic component, comprising a molded product of a permeable magnetic composition according to claim 4.
- 9. A composition according to claim 1, wherein said Ni-Zn-Cu-based ferrite powder has a permeability which is at least 80% of the saturation permeability of the Ni-Zn-Cu-based ferrite.
- 10. A magnetic component, comprising molded product of a permeable magnetic composition according to claim 9.
