Low-profile output choke cores with distributed gap MSC

Product Details

MSC series toroidal cores are made of thin (20+/-2 microns) Fe-based amorphous ribbon and due to their high saturation induction (1.5 T) have a higher inductance rate and the opportunity to operate with a high bias current. Distributed gap, obtained through a special thermomagnetic treatment regime, helps to reduce losses and cost, and to increase technological effectiveness.

Application: mobile devices, miniature DC/DC converters, cell phones, laptops, adapters, car electronics and so on.

KEY FEATURES OF THE AMORPHOUS MATERIAL:

Ribbon thickness 20 microns

Induction amplitude, Bm(25°C) 1.5 T

Curie temperature, Tc 420°C

Crystallization temperature 530°C

Operating temperature range -60°C ... +125°C

Density 7.3 g/cm3

CONFIGURATION:

Ribbon wound magnetic core is placed into hard protective container of aluminum alloy and mechanically fixed with silicone sealant.The container has rounded edges and is designed for direct winding of a thick wire. The container provides reliable mechanical protection and preservation of amorphous material's properties. All materials comply with UL94V-1 / 0.

DIMENSIONS AND KEY FEATURES:

1. outer diameter – inner diameter - height

2. @ F=100 kHz, Urms=1 V, T=25°C

3. The limiting value of the magnetomotive force, defined as the product of the DC bias on the number of winding turns, at which the inductance factor AL is at least 60% of its initial value.

4. Operating temperature range -60°C ... +125°C
