TN9/6/3-4C65 Datasheet PDF - Ferroxcube

●The TN9/6/3-4C65 is a Ferrite Toroid coated with polyamide 11(PA11). Toroid has the best possible shape from the magnetic point of view. The flux path is completely closed so the capabilities of the ferrite are fully exploited. Especially for high permeability ferrites the effect of even a minor air-gap in the magnetic circuit can spoil up to 50% of the effective permeability. A further advantage is the very low leakage field which makes it a suitable shape for power and pulse transformers. Ring cores are mainly used for pulse and wide band transformers and interference suppression coils but also in special power supplies.

● Simple economic shape

● Very low stray flux and leakage inductance

● Not easy to wind
