SMD EMI Fingers / Spring EMI Contacts | 3, 5, 6, 7, 8 & 9 Profiles

SMD EMI Fingers / Spring EMI Contacts provide a low cost way to discharge high frequency interference within RFI shielding requirements.

What can DMTL offer? 

DMTL have a wide range of EMI fingers to help eliminate EMI.

Parts are manufactured from beryllium-copper and are then formed via a unique folding method which helps provide consistent compression characteristics. The parts are then gold-plated which helps provide a low resistance but also a non-corrosive finish.

With circa 50 standard designs available with heights from 0.8mm to 13mm there are a wide range of styles to suit almost all designs. Parts can be customised to specific requirements with relatively low MOQs, due to the unique non stamping, no tooling method of production.

The parts listed in the table below are the following profiles: 

  • 3 Profile
  • 5 Profile
  •  6 Profile
  •  7 Profile
  •  8 Profile
