Premium Soviet/USSR NOS (New Old Stock) Mn-Zn ferrite toroid rings with high permeability (u=2000) are essential for winding custom low-frequency pulse transformers, power chokes, and multi-turn EMI/RFI suppression filters.

Widely used in compact power supplies, signal inductors, line filters, and noise regulators.

Audio application: Highly effective for building custom mains/signal line filters. By suppressing high-frequency RFI/EMI transient noise, they help achieve a cleaner background, improved soundstage definition, and overall better audio clarity.
