Features:

  • Secure and reliable mounting are achieved by flat bottom surface
  • Low profile, low DC resistance, and high current handling capacities
  • High-density mounting can be used due to the magnetic shielding
  • Automatic mounting machines can be used as taped packing is provided

Applications:

  • Mobile phone
  • Personal computers
