Mu-metal shielding
Ultraperm Mu-metal (80% nickel) Shielding Sheet



Mu-metal is effective at reducing induced noise in signal sensitive gear with high gain and small signal levels. If you are trying to achieve the quietness of state-of-the-art hifi, try enclosing transformers with Mu-metal.

Mu-metal shield

Mu-metal is effective at reducing induced noise in signal sensitive gear with high gain and small signal levels. If you are trying to achieve the quietness of state-of-the-art hifi, try enclosing transformers with Mu-metal.

One circular layer (overlapping ends) around a transformer can attenuate by up to 75%.
More wraps = more attenuation.
Best shielding is obtained by enclosing both the source and the device.

Technical Information:
This product conforms to specs ASTM A753 Alloy 4,
MIL-N-14411C Composition 1, and 1J79
