It is mainly used in transformers, chokes, and inductors in switching power supplies, EMI filters, and DC-DC converters.

Powdered iron offers better thermal performance and higher saturation, but ferrite performs better at very high frequencies due to lower core losses.

Yes, within limits. Its lower core saturation compared to ferrite may be a bottleneck for very high-current operations.

Typically available in toroidal or E-core geometries depending on the application requirements.

Yes, its high thermal resistance and moderate magnetic losses make it suitable for both environments.
