TDK EMC Absorber
TDK RF Solutions

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

TDK EMC, RF & Microwave 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 1000°C and possesses physical properties equivalent to those of external porcelain titles.

TDK Styrofoam Absorber (30 MHz to 40 GHz)

Wide Band Cascade Absorber

ITF

TDK ITF Absorber 

 

Data

30 MHz to 40 GHz

It is a composite type radio wave absorber that combines Styrofoam as a support material, a radio wave absorber ITF material that utilizes the ohm loss of the resistance film, and a radio wave absorber material IB material that utilizes the magnetic loss of ferrite.
Resistive film is a material that contains conductive fibers in a mixed organic / inorganic base material and is flame-retardant.
The composite type absorber is designed so that the radio wave absorber IB material efficiently absorbs radio waves in the low frequency region of about 30 to 500 MHz and the ITF material efficiently absorbs radio waves in the high frequency region of 500 MHz or more, making the best use of the characteristics of each loss material. It has excellent radio wave absorption performance from low frequency 30MHz.
*Used in combination with ferrite radio wave absorber IB material.
