WE-STAR-TEC Snap Ferrite with safety key technology

  • Picture
  • Dimensions

Characteristics

  • Prefixing cable system facilitates the cable assembling process
  • Cable clamping protection
  • Internal security locking system with patented key technology (STAR-TEC key) prevents unauthorized removing from the cable
  • One key in each packaging unit
  • Classification of the plastic housing: UL94 V0
  • Operating temperature: –25 °C to +105 °C
  • Core material: NiZn

Applications

  • EMC ferrite for the additional EMI suppression in the frequency area from 1 MHz to 1 GHz
  • Fastening for round cables with diameter 3.5 mm to 25.0 mm or if winded more turns through the ferrite
  • Reusable because of the key technology therefore perfect for test and measuring purposes in EMC labs
