Electromagnetic Compatible (EMC) Products


3M™ Electromagnetic Compatible ProductsControl & Protect Against EMC Threats - Today's Skyrocketing Development of Electronics Requires New Solutions for Significant New Problems

These solutions include an innovative line of 3M™ Electromagnetic Compatible Products (EMC) that are designed to control electromagnetic interference (EMI) from internal sources, limit EMI susceptibility from external sources and help manufacturers meet high certification standards around the world.

3M EMC products help protect and provide for electronic and electrical components in a wide variety of ways - from the manufacturing process to the final product. They are designed to provide electromagnetic compatibility, shield or absorb electromagnetic and radio frequency interference (RFI), ground sensitive electronic components and boards, cushion components, protect cables, provide conductive properties, and add value in other ways. These products also mask and protect PCBs and other devices during manufacturing while minimizing risk from such factors as static charge.

3M offers a wide range of EMI/RFI shielding tapes and absorbing materials, mesh and sleeving products, gaskets and conductive materials, and anti static and high temperature tapes.

Tech Tips
Conductive Foils and Fabrics
In many applications there arises a need to add some conductive material. Different requirements may include EMI shielding, grounding, ESD discharge, or adding conductive paths to existing circuitry. More...
