Magnetics Tape Wound Cores - Square Permalloy 80 01520945D

Square Permalloy 80 For Preamplifiers and Modulators Square Permalloy 80, a non-oriented 80% nickel-iron alloy, is manufactured to meet the high squareness, and high core gain requirements of magnetic preamplifiers and modulators. It is especially useful in converters and inverters where high voltage at low power levels are required, but where circuit losses must be kept to a minimum. Square Permalloy 80 has a saturation flux density approximately ½ that of the Orthonol’s, but has coercive force values 1/5 to 1/7 that of the 50% oriented nickel-iron alloys. Core gain for Square Permalloy 80 is higher by approximately 1.7 times the core gain of Orthonol.
