Noise Supression Sheets (EMC)

tec00002.pngTDK develops and produces magnetic Sheets for RFID (series IFL и IBF) characterising by an extremely small thickness (0.06 - 0.23 mm) and a high magnetic permeability (150-220).

The structure of such magnetic sheets represents a composition: surface film (0.016 mm - 0.038 mm) / Magnetic sheet (0.025 mm - 0.2 mm) / double-sided tape (0.01 mm - 0.03 mm) /release liner. In some variants of technical perfomance the sufarce film and double-sided can be absent.

Magnetic sheets are produced in two variants : separate sheets (size 300mm х 200mm, 125mm х 125mm) and rolls (size 100 mm х 300 mm).


Flexible sheets for EMC providing: series IFL10M, IFL12, IFL16

Advantages:

  • Highly flexible and shock-resistant;
  • High valurs of magnetic permeability;
  • Noise suppression across a wide frequency range;
  • Excellent flexibility in fabrication;

   Application:

  • Reduction of noise emitted from a wide variety of electronic devices (including noise from CPU)
  • Reduction of internal EMI (resonance, crosstalk) inside a shielded casing
  • Reduction of specific absorbed radiation (SAR) from cellular phones
  • Noise reduction for flexible cables used in mobile devices
