IP Absorber Series

IP Absorber Series

​TDK IP Absorber Series consists of a styrofoam base and an electromagnetic absorber that uses the magnetic loss of ferrite.

TDK IP-BLB Absorber Series is a composite electromagnetic absorber (RF foam absorber) comprising a base material of styrofoam combined with IP radio wave absorber, which is known for its ohmic loss properties, and IB material, which is a ferrite radio wave absorber. IP-BLB Absorber was developed for anechoic chambers.

Our composite absorbers fully utilize the features of each loss material. In the 30 to 500MHz range the IB electromagnetic absorbers, and in the higher range of 500MHz and higher the IP electromagnetic absorbers, are designed to provide efficient electromagnetic absorption and deliver excellent electromagnetic absorption performance for frequencies as low as 30MHz.

*Used in combination with a ferrite radio wave absorber IB material.

  • Ultra-wideband electromagnetic absorber.
  • Stable against acids, bases and water vapor, and offers long service life.
  • Uses materials that, when burned, emit gases that are relatively harmless to humans.
  • Fire retardant (NRL Classes 1, 2 and 3; UL-94HBF).
  • White end caps (sold separately) improve the illumination inside the chamber.

TDK’s composite electromagnetic absorbers highly praised around the world. These unit-configured electromagnetic absorbers are small, lightweight, inexpensive and deliver excellent electromagnetic absorption performance over a wide bandwidth. They are used widely in anechoic chambers for 3- and 10-meter ranges as well as in large anechoic chambers designed for specific applications.
