Amidon ferrite toroids calculator
| Material type of the toroid – | ||
| Dimension type of the toroid – | ||
Available information about the toroid:
Initial magnetic permeability (μ):Saturation flux density (Bs): Gs
Residual flux density (Br): Gs
Coercive Force (Hc): Oe
Curie Temperature: °C
Dimensions (OD x ID x H):
AL factor: nH/N2
ENTER THE INPUT DATA:
| L | = | – Required inductance |
| N | = | – Number of turns |
The calculator uses the formula:
L [nH] = AL*N2

Material 43 is used for EMI/RFI suppression in the 20 MHz to 250 MHz range.
Material 52 which is made of a new NiZn Ferrite material, combines a high saturation flux density and a high Curie temperature.
Material 61 is designed for inductive applications up to 25 MHz and also suppresses noise frequencies from 200 MHz to 1000 MHz
Material 67 is for high Q inductors up to 50 MHz. Suppresses frequencies above 1000 MHz.
Material 68 is non-standard and only in stock on a few sizes. High Q up to 100 MHz.
Material 75 is used for excellent attenuation from 0.5 MHz to 20 MHz
Material 77 is used as ferrite toroid coil forms for transformers, inductors and RFI suppression.
Material F has high saturation flux density at high temperature. For power conversion transfomers. Good noise suppression from 0.5 to 20 MHz.
Material H has very high permeablity.
Material J has low volume resistivity and low core loss from 1 KHz to 1 MHz. Used for pulse transformers and low level wideband transformers. Excellent frequency attenuation from 0.5 MHz to 20 MHz.
Material K is used primarily in transmission line transformers and baluns from 1 MHz to 50 MHz.
Material W is a high permeability material used for frequency attenuation from 100 KHz to 1 MHz in EMI/RFI filters.
