Product Description

Introduction：

Nanocrystalline cores does not have mechanical strength ,it's not suitable to wind directly on it. So it will usually pack by plastic case or by epoxy resin spraying.

The nanocrystalline magnetic core coating adopts high temperature epoxy resin powder spraying process, with a layer of 0.2 ~ 0.7mm (depending on the product) coating on surface of the cores, which is used as the insulating layer of core and has a certain mechanical strength.

Typical Application：

New energy applications (PV lnverter, wind driven generator, EV charging station)
Consumer Appliance(TV, AC, computer, game console)
Medical equipment (MRI machine, ventilator)
Other electronics(Server power supply, UPS, Railway)

Performance Characteristics：

High Bs, high μi	High Bs (1.2T), high μi (>80000), and high anti-saturation ability, can reduce the core’ s volume effectively
Excellent frequency property	Excellent permeability characteristics in a wide frequency range
Stable temperature characteristic	The performance change rate is ±10% during temperature -40°C~150°C
With high broadband property	Suppress 150kHz~300mHz conduction and radiation interference
Low magnetostriction coefficient, low noise	Saturated magnetostriction coefficient is close to zero λs≈0
