Shielding Effectiveness of Expanded Metal Foils

Careful circuit design can minimize EMI, but additional shielding measures are often required.

Expanded metal foils are versatile, effective EMI shielding materials. EMFs are formed from thin metal foils, creating a lightweight, strong and flexible sheet material. Expanded copper foil is commonly used for EMI shielding, but aluminum, nickel, Monel and stainless-steel foils can also be used when there are unique specifications.
