YSHIELD® MCF5 | Magnetic field shielding film | Width 5 cm | 20 metre roll

MCF5 is a magnetic shielding film made from an amorphous cobalt alloy for shielding of low-frequency alternating magnetic fields. Also shields low-frequency electric alternating fields (LF) and high-frequency fields (HF). Because MCF5 has a width of only 5 cm, it’s recommended for shielding smaller areas, e.g. in electronic applications or for cables.This product will not shield fixed/permanent magnetic fields. MCF5 stays flexible but hard even at small bending radii. The attenuation remains constant even at high mechanical stress. MCF5 can easily cut with scissors.

Processing

Warning: The cutting edges are extremely sharp! It is recommended to use our plastic scraper FVR10 to press it on the adhesive tapes or into the glue to save cutting your fingers! There is no self adhesive version available. However, bonding is easily possible with a double sided adhesive tape e.g. carpet adhesive tape with 50 mm width or a wider double-sided adhesive tape. Otherwise a commercial surface contact adhesive can be used.

Grounding

Due to the conductive surface this material can be contacted and grounded easy to shield low frequency (LF) electric fields.

Shielding attenuation

The shielding attenuations are regularly tested in YShield’s own laboratory, HF due to ASTM D4935-10, the LF magnetic field due to ASTM A698/A698M-07. Please see the test reports below.
