T157040 Magnetic Loop Inductor
Composite magnetic core inductor designed for high power density applications with exceptional high-current tolerance. Features innovative combination of iron silicon aluminum and ferrite materials for superior performance.
Product Overview
The T157040 magnetic core inductor combines iron silicon aluminum and ferrite materials, delivering magnetic flux density twice as high as traditional ferrites. This enables greater energy storage in the same volume, making it ideal for high-current applications ranging from a few amperes to hundreds of amperes.
