Features & Application
． Mounting on the surface of NR inductors has high power current sensing.
． NR inductors are small in size and are miniaturized products,
but the chip inductors have high quality, huge storage capacity and low resistance characteristics
．Surface mount high power inductors.
．Reel packaging is available for automatic surface mounting.
．It has the characteristics of high Q value and low impedance
Low magnetic leakage, low direct resistance, high current resistance and a series of features.
It is widely used in notebook computers, desktop computers, servers, plug-ins,
TVs, smart homes, LED lighting, automotive products, wireless remote control systems,
low-voltage power supply modules and other electronic equipment.
