Fe-based Nanocrystalline Ribbon

Description

Fe-based Nanocrystalline Ribbons can be utilized to supplant silicon steel, Permalloy, and ferrite as brilliant materials to make transformer centers for high-recurrence switch mode control supplies.
Nano crystalline cores are Iron Based cores which is an uncommonly grown delicate attractive material with low magneto striction, high penetrability immersion transition thickness of 1.25t and working temperature of 120 degrees celsius or more. Nanocrystalline cores are accessible in type of toroidal or stadium formed tape-wound centers. The material itself is fragile and requires an insurance against mechanical powers, which is either given by plastic core boxes or a reasonable warmth resistive covering. Once covered or boxed, the centers are amazingly hearty and the major attractive properties are highly linear and not very much dependent from temperature.
CATECH Nanocrystalline cores has been considered as THE finest material for transformer making.

Application

EMC Common Mode, Normal Mode Filter Chokes.
Cores for main transformer of switch power supply and control transformer.
Different Accuracy CT/VT Cores.
Mag-amp and pulse killer cores.
