For EMI-noise suppression in Switched-Mode Power Supplies, Frequency Inverters and many other
Applications, tape-wound cores made of iron-base nano-crystalline 1K107 offer significant advantages in
Volume and performance. The material property, such as high initial permeability in graded permeability
Levels between 30 000 and 80 000, high saturation flux density, low core losses and an extended
Operational temperature range.

Common mode chokes with nano-crystalline cores offer the following features:
1, High inductance with a low number of turns and small winding capacities.
2, Broadband insertion loss curve with good damping performance over a wide frequency band.
3, Small choke size for volume- and weight optimized solutions.
