Effective shielding Easily installed Anti-Electro-Magnetic Interference Excellent anti-corrosion Custom shapes available

Shielding case is a major protecting method in magetic fields, which obtains double actions: one is to prevent or reduce the electromagnetic interference from outer field, the other is to prevent or reduce the part-'s own electromagnetic field affecting any other relevant parts.

Shielding cases including one-piece shield, two-piece shields and multi-compartmental shield are packaged for surface mount applications for a wide range of industries.

The material required for shielding are mainly conducting materials with low resistivity & high permeability. The most effective magnetic shielding material available is mu-metal, an alloy of 77% nickel, 16% iron, 5% copper, and 2% chromium, which is then annealed in a hydrogen atmosphere to increase its permeability. As mu-metal is comparatively expensive, other alloys with similar compositions are also applied for magnetic shielding, which contains around 80% nickel.
