ETD Cores

ETD Cores

ETD Cores are an inexpensive option to use for transformers and inductors. Their dimensions assure minimum winding resistance and optimum efficiency. However, the cores are highly-priced than E cores even though they offer less productivity. They are available in a variety of sizes such as ETD2910, ETD3411, ETD3411A, and ETD3913. Common applications for ETD cores are differential inductors and power transformers.
