The DN45 ferrite material from TDK Corp. is designed for use in pulse transformers for 100Base-T systems and boasts a high inductance feature over a wide temperature range.

Under a dc biased condition of 8mA, the company said that the DN45 achieves a better performance than the conventional HP5 material, and enables 20 percent fewer coil turns under same drive conditions in 100Base-T pulse transformers. These results to improved transmission properties, as well as smaller pulse transformer devices.
