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.
Pros
- Economical
- Minimum winding resistance
- Optimum efficiency
Cons
- Expensive than E Core
- Productivity is less
Applications
- Differential inductors and power transformers
