Noise suppression bead cores cobalt based amorphous for single-turn chokes MSB

Product Details

The cores of MSB series are made of thin (18 +-2 microns) Co-based amorphous ribbon, have square B-H loop and have much higher permeability than their analogs made of Fe-Ni-based permalloys and ferrites.

The product's design is optimized for use with single-turn coil, which is usually component (transistor, diode) output.

KEY FEATURES OF THE AMORPHOUS MATERIAL:

· Induction amplitude, Bm (25°C) 0.62 T

· Induction amplitude, Bm (90°C) 0.54 T

· Squareness ratio Br/Bm (@ 100 kHz, 80 A/m) at least 0.90

· Curie temperature, Tc 225°C

· Operating temperature range -60°C ... +100°C

· Magnetostriction less than 0.1´10^-6

CONFIGURATION:

Ribbon wound magnetic core is placed into hard protective container of glass-polyamide and mechanically fixed with silicone sealant. The container provides reliable mechanical protection and preservation of amorphous material's properties. All materials comply with UL94V-1 / 0.
