Nanocrystalline Fe-based Common Mode Choke Toroid Cores with High Permeability MSFN-T

Product Details

Toroidal magnetic cores are made of thin (18 -20 mm) Fe-based nanocrystalline ribbon and have high permeability in a wide frequency range, high saturation induction, low-loss, increased operating temperature (up to 120 ° C), good thermal stability. T

Magnetic cores have typical valuation of magnetic permeability 90 000 (at frequency 10 kHz) and more.

3. Annealing in transverse field , flat hysteresis loop.

4. KEY FEATURES OF THE MATERIAL:

· Induction amplitude, Bm (25°C) 1.2 T

· Induction amplitude, Bm (90°C) 1.1 T

· Curie temperature, Tc 570°C

· Operating temperature range -60°C ... 120°C

· Magnetostriction less than 0.5´10^-6

· Typical permeability (10 kHz) 90000

· Typical permeability (100 kHz ) 30000

· CONFIGURATION:

Ribbon wound magnetic core is placed into hard protective container of glass-filled polyamide or aluminum alloy and mechanically fixed with silicone joint sealant. The container has rounded edges and is designed for direct winding of a thick wire. The container provides a reliable mechanical protection and preservation of nanocrystalline material's properties. The new series is also available without container, with epoxy high-temperature powder coating (MSFNP-TH). All materials conform to standard UL94V-0/1.
