Which EMI shielding material is better?

Hello,

I have a little bit problem on choosing which EMI shielding material I should buy. I have found these 3 materials from element 14 and can give me some advice or suggestion which one to choose or any other recommendation?

I want the EMI shielding sheet to cover the electronic circuit board.

1 Wurth Elektronik 354002354002 Ferrite Sheet Shielding Square 120mm

2 Laird Technologies WS-8463-NAWS-8463-NA Shielding Sheet RFI/EMI

3. 3M CN-3190 Sheet, Polyester, Flat, 70DB

Thank you.

Regards,

Wai Lynn

Shielding
Many factors determine the true shielding effectiveness of a shielding tape, including
Effectiveness
type and thickness of foil adhesive type,
intimacy of contact, smoothness of
application surface, strength and frequency
of the EMI signal, etc. However, using
standard tests and fixtures it is possible to determine a value for the attenuations. For
CN-3190 fabric tape, typical shielding effectiveness is in the range of 65dB to 70dB.
Before using this product, the user must evaluate it and determine if it is suitable for
the intended application.
