Tape Wound Cores

Tape Wound Core, Bobbin Core, Square Orthonol, Square Permalloy 80,  Supermalloy, 48 Alloy, Magnesil, Supermendur, Round Permalloy 80,

Magnetics® Tape Wound cores are often key components of complicated electronic circuitry found in high reliability applications including military, aerospace, communications, down hole drilling, and nuclear reactors. Tape wound cores and Bobbin cores are made from thin strips of high permeability nickel-iron alloys such as Square Orthonol®, Square Permalloy 80Round Permalloy, Supermalloy, and 48 Alloy, or grain oriented silicon iron known as Magnesil®.  Specific applications for tape wound cores include magnetic amplifiers (MagAmps), converter and inverter transformers, current transformers, and static magnetic devices.
