E core inductor online calculator:
This calculator is designed to calculate the number of windings of a coil on a ferrite E core for a required inductance. The peak current limited by core saturation is calculated assuming a maximum magnetic flux of 0.3T for most ferrites. For an iron core this current is at least 3 times higher.
ENTER THE INPUT DATA:
| Select units: |
| L | = | – Required inductance |

| E | – Dimension E | |
| F | – Dimension F | |
| b | – Slot size | |
| g | – Center-post gap | |
| μr | = | – Relative magnetic permeability |
