TDK Ferrite Material PC47/PC90/PC95

TDK corporation has introduced the PC47 Power Material as the next generation power material to replace both PC40 and PC44 power materials. The greatest 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. This is the material for new designs and to replace PC40/PC44 for greater efficiency.

TDK power core offers a three pack of power; PC47 for the lowest possible losses at 100°C, PC95 for low core losses over a wide temperature range and PC90 for high Bsat for output chokes.

TDK Ferrite Material PC40/PC44

TDK PC40 and PC44 material has been the "power material standard" for many years. The PC40 material was the first ferrite material designed for over 100KHz operation. As power supply frequencies continue to increase over the 250KHz region, the usage of PC40 and PC44 has been decreasing. The PC47 material is taking the place of PC40 and PC44 at all operating frequencies. The below files are provided for use as reference only. All new power designs will be in the three primary materials – PC47 – PC90 – PC95
