- Industry standard for RF and Audio Applications
- Carbonyl Iron mix - exclusively from Micrometals
- High Q up to 40 MHz
- Used for moderate band transformers 200 to 400 MHz
- Permeability of 10μ
- The low permeability results in lower operating AC flux density than
other materials with no additional gap‐loss.
- For a slightly higher permeability consider -14 material.
