TDK Ferrite Cores

TDK was founded in 1935, to commercialize the magnetic material “ferrite.” For more than 70 years since then, TDK has enriched the materials technology down the stream of ferrite, the process technology to extract the most out of such materials, and the evaluation and simulation technology. Through these, TDK has developed and provided a variety of products of value and originality to the society.

Today, amid the progress of digitization and advanced information networking, the manufacturing of TDK that fully utilizes its core technologies gave birth to a wide range of products, from hard disk drive heads, multilayer ceramic chip capacitors, inductors, sensors, noise management parts and others. These products representing TDK have been supporting the progress and the spread of mobile equipment and home information appliances.

The electronic technology is now on the stage of yet another breakthrough. The electronic technology has brought big dreams and benefits to people’s life. But, yet further development is expected of it, and the role of the electronic materials and the electronic components that are essential to the progress of the electronic equipments will become more and more important.

TDK Ferrite Material PC47/PC90/PC95
The Three Pack For Power

TDK corporation has introduced the PC47 Power Material as the next generation power material to be used in NEW designs. The advantage of PC47 is the lowest possible core losses (250 KW/M3) at 100°C, 100KHz and 200mT. The saturation is also improved to be greater than 420mT at 100°C.

TDK power core offers a three pack of power

1.	PC47 for the lowest possible core losses at 100°C
2.	PC95 for low core losses over a wide temperature range (-40°C to +120°C)
3.	PC90 for the highest saturation of any MnZn ferrite with relatively low losses. PC90 can be used for both: High B_sat for output chokes Power Transformers where high B_sat is critical
