Introduction to common coding rules for nanocrystalline cores -

Nanocrystalline and amorphous soft magnetic cores have excellent comprehensive magnetic and electrical properties such as low magnetic induction, low magnetic permeability, high core loss and good high-frequency characteristics. Compared with traditional soft magnetic materials such as ferrite, silicon steel, and permalloy, it has a lower performance-price ratio, and is widely used in low-tech industries such as modern communications, power electronics, electromagnetic compatibility, and sensors, especially limited to lightweight, high-frequency , low-efficiency inductor and transformer product design. According to the classification of application fields, nanocrystalline and amorphous soft magnetic cores include the following brand series: FJ series non-gap amorphous inductance cores and wire wound inductances, FG rings and C types for car audio, FPC, differential mode and smoothing filters Notched inductance core and wire wound inductor, WUL type high inductance core and wire wound inductor for differential mode and smoothing filter, EMC common mode anti-interference filter WWL type nanocrystalline core, switching power supply, inverter power transformer and single Low remanence CL type cobalt-based amorphous magnetic core for polar pulse, CB and CZ type cobalt-based amorphous core for low remanence high-frequency power transformer, peak suppression and magnetic amplifier FX type iron-based composite core and cobalt-based wide Constant permeability magnetic core, precision DC transformer C-type and rod-shaped magnetic core and winding inductor Large current (50-250A) chopping, differential mode and smoothing filter
