Benefits
- Significantly smaller build volume (up to more than a factor of 3)
- Satisfy both high saturation magnetic flux density and high permeability long with low coercivity
- Makes the single stage filter designs possible
- Low core loss (approximately 1/5th of the Fe based amorphous metal)
- Low magnetostriction, thus less affected by mechanical stress
- Low number of turns required for high L, thus reducing number of filter stages
- High efficiency, hence low power loss and hence less use of material makes it eco friendly
- Very low audible noise emission
- Less copper loss due to reduced number of turns
- Aging effects are very small unlike Cobalt amorphous metals
- Epoxy coated fiber glass tape/casing is resistant against mechanical stress
- Excellent high frequency characteristics as the values of permeability and core losses remain high and low respectively at very wide range of frequencies.
- Extended temperature range from -25… + 120ᵒC (standard) /180ᵒC (special) due to high curie temperature, thus making material properties nearly independent of temperature
