TDK EMC, RF & Microwave Absorber
TDK RF Solutions

TDK is the only company that manufactures both the ferrite tile and the complementary foam absorber.

This is both advantageous and critical for both low and high frequency performance, high power dissipation, and broadband behavior. TDK uses very sophisticated manufacturing techniques to create both our ferrite and our foam absorber materials. These techniques allow us to control every parameter of the materials which impact performance and safety. By adhering to strict quality production checks throughout the creation process, we can bypass many time consuming and unnecessary steps (e.g. having to measure each piece of absorber product for size tolerance and RF parametric compliance). The result is a much more efficient production process with a higher yield rate for absorber products.
Catalog
In addition, the facilities in which these products are manufactured are completely managed under an ISO 9001 quality system and an ISO 14001 environmental management system. With over 300,000 m2 of production capability, TDK manages the largest such facilities worldwide.

Product Overview

TDK, the world's largest supplier of ferrite material, ferrite products and EMC components, is the undisputed leader in ferrite tile and cascade radio wave absorber technology. TDK developed the concept of ferrite tile as EMC radio wave absorbers, and has over 20 years experience in constructing anechoic chambers with ferrite tiles.

IB Material

This electromagnetic absorber utilizes the magnetic resonance loss characteristic of ferrite. This sintered ferrite has been baked at a temperature of over 1000C and possesses physical properties equivalent to those of external porcelain titles.

IB-017

This is a sintered ferrite and delivers excellent electromagnetic absorption performance particularly in the VHF band. This extremely thin electromagnetic absorber is 5.2mm thick.

Features

This is a thin-type wide-band electromagnetic absorber.
This is highly weather resistant.
Can be used as building material.
