Cores

Toroidal Strip-Wounds Cores from Amorphous and Nano-Crystalline Alloys

• O.D.: 3 – 150 mm
• Height: up to 40 mm
• Low specific losses, small coercive force and residual induction at high frequencies (20 – 400 kHz)
• Increase efficiency of devices operating at high frequencies, provide considerable mass and device dimensions, reduce overheating and increase transformer efficiency
• Cores can be custom-made according to customer’s specifications

Toroidal Amorphous MH Cores with Saturation Mode

• MH cores, wound from amorphous alloys on Co-base, with rectangular hysteresis have high squareness, low losses and low coercive force at high frequencies.
• Applications include magnetic amplifiers for power supplies with switching mode, pulse transformers, current transformers, transformers for self-exciting inverter and other saturation devices.
• Toroidal Cores of the type MA from Amorphous Alloy with DC Bias
• Capped core of the type MA, wound from Fe-base amorphous alloy, are effective and reliable at high frequencies in tens and hundreds kHz. Main features include high saturation induction, Bs = 1.5 T, very low core losses at high frequencies and high level of DC bias at high permeability.
• Applications include output chokes with DC bias, chokes of power ratio correction, chokes of power supply filters with high frequency switching mode and inverters circuits.
• Cores can be custom-made according to customer’s specifications

MN Toroidal Strip-Wound cores from Amorphous Alloy

• MN cores, strip-wound, from Co-base amorphous alloy with rectangular hysteresis, have unique properties: low losses, low coercive force and high squareness ratio at frequency of 100 kHz and higher in comparison with cores from permalloys on the base of Fe-Ni.
• MN cores allow increased efficiency of modern devices, operating at high frequencies, and provide miniaturization of electronic and electric equipment and enable excellent high frequency characteristics.
• Applications include modern devices for noise suppression at frequencies for tens and hundreds kHz.
• Cores can be custom-made according to customer’s specifications
