ETD Cores can be utilized for both transformers and inductors, making them a cost-effective alternative. The dimensions of them ensure lower winding resistance and better efficiency. Though the efficiency and performance are lower than E cores, the increased cost of Cores is solely due to the processor, which costs as much in numeric numbers. They are available in a variety of sizes, including ETD2910 and ETD3411, ETD3913, ETD4415 etc
Applications: ETD cores are widely used in differential inductors and power transformers.
