EMI Shielding Finger Strip Gasket

  • microwave shielding finger gasket
  • EMI Shielding Fingerstrip Gasket
  • EMI Shield Finger Gasket

Overview

  • EMI shielding finger strip gasket is made of Beryllium Copper (BeCu) alloy as the primary material, which is elastic and robust against metal stress. It is used for electrical surge grounding and electromagnetic shielding.
  • It has excellent shielding effectiveness due to low contact resistance and resistant to corrosion by plating tin and gold on its surface.
  • SMD type is provided in an embossed carrier tape for packaging to enable automatic surface mount (SMT)
  • Why grounding in electronic devices

Features

  • Beryllium copper as the primary material is used.
  • It has low contact resistance and excellent corrosion resistance.
  • Embossed carrier tape packaging for automatic surface mounting (SMT)
  • RoHS Compliant
