Properties of bobbin materials

NV bobbins and SV bobbins are equivalent products, and are effective when used in combination with PENVW wires
By using a combination of RA bobbin material and NH (EN) RAW wire, the synergistic effect of heat resistance will maximize temperature resistance and adhesive strength

コーディング構造

Features

Hz+S treatment method is used to create an insulating layer on the metal bobbin material, which prevents short-circuiting of both the metal bobbin material and the magnet wire

コーディング構造

Features

S+S processing method is used to increase the strength of the flat part of the elliptical (track) coil and the R-curved surface, which improves the adhesive strength and prevents poor adhesion and dropping of the bobbin and magnet wire

コーディング構造

Features

The special treatment method of H is used for H-wise voice coil. It avoids winding defects in the wire alignment that occur with horizontal or vertical winding

Conducted comparative testing of insulation and solubility between Nikkay's NV metal bobbins and SV metal bobbins produced by other manufacturers

Nikkei's bobbins have an insulating layer on the metal material, and the insulating layer remains even after dissolution experiments with alcohol
