Ferrite Cores – The Versatile Standard:
Ceramic materials based on manganese-zinc (MnZn) or nickel-zinc (NiZn), offering high permeability and suitable for mid to high frequencies (kHz to MHz).
- MnZn: Best for lower frequencies (< 2 MHz)
- NiZn: Best for higher frequencies (> 1 MHz)
- Advantages: Cost-effective, widely available in shapes like toroids, E-cores, and RM cores, low eddy current losses at high frequencies compared to iron cores
alfatec offers a broad range of ferrite core coils and bobbins, including from partner Sunlord.
Nanocrystalline Cores – High Performance for High Frequencies:
Made from alloys with ultra-fine grain structures via special heat treatment.
- Technical Specs: Very high permeability, excellent frequency response, low core losses, good thermal stability
- Advantages: Higher performance than ferrites, ideal for common-mode chokes (CMCs), allows smaller designs for the same power
Ideal for EMI applications and high-performance power supplies.
Amorphous Cores – Efficient at High Frequencies:
Made from rapidly cooled metal alloys with no crystalline structure.
- Technical Specs: High permeability, low coercivity, low core losses
- Advantages: High efficiency, suitable for SMPS, output chokes, and PFC chokes
A good alternative to ferrites in specific designs.
Iron Powder Cores – Robust and Cost-Effective:
Composed of fine iron particles insulated and molded with a binder.
- Technical Specs: Moderate permeability, high saturation flux density, suitable for lower frequencies (100–300 kHz)
- Advantages: Excellent DC bias behavior, stable inductance under high DC currents, robust, low cost
Ideal for storage chokes in DC/DC converters and PFC applications.
