Product Description

Nano-crystalline Ribbons
We produce iron-based Nano-crystalline ribbons for distribution transformer cores.
We also produce iron-based amorphous and cobaltbased amorphous for a
Variety of electromagnetic components in electric and electronic fields.

Application Fields:

Medium frequency transformer cores in heating equipment
Toroidal gapless cores as SMPS output inductors, differential input inductors
Toroidal gapless cores as noise preventive chokes in car audio, car navigation system
Toroidal gap cores for PFC use in air conditioner, plasma TV set
High frequency rectangular cut cores as output inductors and transformers in SMPS, UPS etc.
Toroidal gapless cores as pulse transformer for driving IGBTs, MOSFETs and GTOs
Amorphous stators and rotors in high power density variable speed electric motors and generators
Characteristics:

Highest saturate induction among amorphous alloys- Reduce component volume
Low coercivity- Promote component efficiency
Low core loss- Reduce device temperature rise
Variable permeability - Satisfy the various application requirements depending on different core heat treatment
Excellent stability- Having highest serving temperature of 130° C
