Ferrites

• Impeder cores are an essential accessory for welding tubes and pipes using high frequency waveguide heating.

• Thanks to the new standards for ferrite cores with distributed air gaps, TDK enables increased power density and a further degree of downsizing compared to other technologies. In addition, cores with distributed air gaps offer the possibility to optimize the design of transformers and chokes in terms of efficiency and thermal performance.

• New Power Material PC200 for Switching Frequencies up to 4 MHz
• Besides the ELP core series that range from ELP 14 to ELP 102, TDK offers extended series of EPCOS planar cores with round center posts in the ranges ER 9.5 to ER 32 and EQ 13 to EQ 30. 

The E series materials for EMI applications include E11 for wide frequency filtering (30-300 MHz), E12 with flat initial permeability up to 30 MHz, E13 and E14 with high saturation and impedance up to 30 MHz, and E16 and E19 for noise suppression below 10 MHz.
