Tape Wound Cores: Square Orthonol

What is Square Orthonol?

For more technical information please look at the official Magnetics Strip Wound Core Design Manual.

Square Orthonol, a grain-oriented 50% nickel-iron alloy, is manufactured to meet exacting circuit requirements for very high squareness and high core gain, and is usually used in saturable reactors, high gain magnetic amplifiers, bistable switching devices, and power inverter-converter applications. Other applications such as time delays, flux counters and transductors demanding extremely square hysteresis loops require selection of Square Orthonol.
