    AI Overview
    Magnetic Field Shield Materials EMI Electromagnetic ...
    Mu-metal shielding cans are high-permeability (approx. 80% nickel-iron) enclosures used to protect sensitive inductors and transformers from low-frequency magnetic interference, preventing EMI and crosstalk. They work by providing a low-reluctance path that diverts magnetic flux around the component, typically offering superior shielding in high-end audio and sensitive electronics. 
    Key Features and Options 
    • Shapes & Sizes: Available in round and rectangular shapes, often with lids (inside or outside fitting) to create a fully enclosed shield.
    • Production Methods: Cans can be deep-drawn for seamless construction or fabricated for custom, multi-layer designs.
    • Thickness: Standard thicknesses range from 0.014 in to 0.062 in (0.36 mm to 1.58 mm).
    • Customization: Custom sizes are common to fit specific inductors. 
    Application & Performance 
    • Efficiency: They offer high attenuation of magnetic fields, particularly in the 100 kHz range.
    • Mounting: They can be mounted on PCBs or inside cabinets to reduce transformer hum.
    • Handling & Care: They require careful handling, as bending or shocking the metal can degrade its high-permeability magnetic shielding properties. If deformed, they may need re-annealing. 
    Common Manufacturers/Providers 
    • Magnetic Shield Corporation (MuMETAL®): Provides stock and custom shielding cans.
    • Don-Audio (MigMa Mini MuCan): Specializes in shielding cans for transformers and electronics.
    • MuShield: Provides design and manufacturing.
    • Hongertech: Produces Ni80 Mu-metal shielding covers. 
    For high-intensity fields where Mu-metal might saturate, multi-layer shielding using a combination of Ni80 (Mu-metal) and higher saturation materials (like Co-NETIC® or electrical steel) is recommended.
