Electrically conductive self-adhesive EMI tape

Swelex offers electrically conductive EMI tapes that protect your electronics from interference and safety hazards. 

How to choose the right self-adhesive shielding tape for electronics

If you need to protect your electronics from interference or create a secure electrical connection, conductive EMI tape or self-adhesive shielding tape is a smart and easy solution. This type of tape, also called EMC tape for electronics, is used to block unwanted signals (EMI/RFI) and to create electrical grounding or contact in a smooth way.

What is electrically conductive EMI tape?

Electrically conductive EMI tape is a thin, self-adhesive tape consisting of a layer of metal - such as aluminium or copper - and a special adhesive that also conducts electricity. The tape is flexible and can be easily cut to the right length, width or shape to suit your particular application. It is often used to protect electronics from interference, to earth components or to create temporary electrical connections during testing.

Why should I use EMC tape for electronics?

• Protects your electronics from interference (EMI/RFI)
• Easy to use and apply - just cut to length and press into place
• Works on many different surfaces and materials
• Can be used for both temporary tests and permanent installations
• Available in different materials and sizes to suit your needs

Which type should I choose?

Material: 

• Aluminium tape is lightweight, affordable and suitable for most common shielding and earthing applications. 
• Copper tape has very high conductivity and is especially good for sensitive electronics or where you know you will need to solder on the tape
• Tin-plated copper or nickel tape is used when you need extra protection against corrosion or want a special finish

Thickness and width:

The tape comes in different thicknesses and widths. Thinner tape is more flexible and easy to mould around corners, while wider tape covers larger areas and provides extra protection. Swelex also offers customised die-cut shapes to drawing for specific applications.

Field of application:

• For permanent protection and earthing: choose a tape with strong adhesion and high conductivity
• For temporary solutions and tests: choose a tape that is easy to remove and possibly even reuse
