Nippon Chemi-Con FL-V Series Common Mode Choke Coils with High-performance, Small-size Products and High-magnetic Permeability
Nippon Chemi-Con has developed Common Mode Choke Coils FL-V Series with permeability at 100kHz increased to 200% compared to conventional products. The Series contributed to the downsizing of switching power supplies and inverter power supplies.
Nippon Chemi-Con has commercialized the FL Series as common mode choke coils using nanocrystalline for magnetic material and sold them as noise filters for power supply input/output and DC line noise filters.
The FL-V Series achieves improved performance and smaller size and lighter weight through improvements in magnetic materials.
Compared to the conventional FL Series, the permeability at 100kHz is improved to 200% while maintaining the permeability at 10kHz and without lowering the resonance frequency.
In addition, the product size with equivalent performance at 100kHz can be reduced by 35 to 40%.
The switching frequency of power supplies and the control frequency of inverter power supplies tend to increase as the equipment becomes smaller and achieves more advanced features. In addition, there has been an increase in the number of devices that generate noise accompanying the advance of electronic control of automobiles and the spread of EVs and PHEVs.
Nippon Chemi-Con proposes the FL-V Series as an effective product for noise reduction of such equipment.
