MEDER springs: tiny champions with a big impact

EMC springs

Spring elements for the prevention of electromagnetic interference. Professionally manufactured EMC springs for electromagnetic compatibility are an advanced solution in the electrical and automotive environment.


Technical devices should not interfere with each other as a result of unwanted electrical and electromagnetic effects. To ensure that this does not happen, contact elements made of strip material or wire are used. The spring elements prevent electromagnetic fields and absorb mechanical vibrations. Solderless contacts via the contact pressure of the spring force allow a safe and cost-effective option for connecting components electrically. For optimum automated further processing using pick and place or SMD loading, we offer a range of different types of packaging (e.g. tape and reel).


  • Strip thickness 0.04 – 0.80 mm
  • Strip width: 0.30 – 30.00 mm
  • Wire ø 0.03 – 2.00 mm
