Packaging

as per request

Product Details

Toroidal magnetic cores are made of a Fe-based thin (20 microns) nanocrystalline ribbon and have low loss, high induction of saturation, high operating temperature (up to 150 °C), high magnetic permeability. Magnetic cores have a negative temperature coefficient of losses that provides stabilization mode transformer temperature.

Application in power high- frequency transformers push-pull,bicyclic SMPS, DC-DC converters, audiotransformers.

High permeability provides good electromagnetic connection of windings and low leakage inductance values.

HIGHLIGHTS OF THE MATERIAL:

· Induction amplitude, Bm (25 ° C) 1,2 T

· Induction amplitude, Bm (90 ° C) 1,1 T

· Curie temperature, Tc 570 ° C

· Magnetostriction less than 0,5 x10 ^ -6

· Magnetic Permeability (100 kHz) - up to 20,000

1) Operating-temperature range in plastic container from -60°C to +120°C;
2) Either with epoxy coating from -60°C to +150°C;
3) If used epoxy coating, dimensions can be changed on at the customer's request.

СONFIGURATION:

Magnetic cores are available in two versions:
1. In a hard protective container of glass-filled polyamide. Operating temperature range from -60 to +120 ° C. The container has rounded edges and is designed for direct application to a thick wire winding. Container provides a reliable mechanical protection of nanocrystalline material and the preservation of its properties.
2. With special high-temperature epoxy powder coating. Max range of operating temperatures from -60 to +150 ° C.

All materials conform to standard UL94V-0/1.
