BandSorb HP Series

BandSorb HP series is a thin high permeability ferrite sheet designed to have low losses at 13.56 MHz. The high permeability makes it ideal to use for NFC, RFID application & wireless charging application.

BandSorb HP series materials can be supplied in sheets as well as custom configurations, standard sheet size is 125 mm x 125 mm.
The BandSorb HP consists out of ferrite covered with a protective film on one side and adhesive tape on the other side.

Features and Benefits:
High magnetic permeability, low loss
RoHs, Halogen Free

BandSorb HP series can be used to improve the performance of:

  • NFC antenna for mobile phones and automotive.
  • NFC or RFID antenna for security & access control system.
  • Wireless charging for mobile phones and battery powered handheld electronic devices
