Common mode choke core
Product Profile :
WENERGY will select ribbon with suitable composition and level to wind cores based the performance requirements from customers. Then cores will be annealed in magnetic field to meet customers’ requirements. Finally cores will be packaged according to customer’s requirements. |

► Features ( Common mode choke core ) :
The EMC standard of frequency range of 150KHz-30MHz on restraining the conducted CM EMI are becoming more serious in the application. CM inductance & filter capacitor were used to restrain the CM EMI. Ferrite core or common Nanocrystalline core are popular in domestic market as common mode choke cores, but high high-frequency volume and impedance reduction from 150KHz to 30MHz due to the operating frequency limitation makes these cores unworkable. In this case , we developed advanced higher property Nano-crystalline common mode choke cores as solution for EMC common mode choke cores requirement, and were applied to the EMC of switch power modules, UPS power supply, communication power supply, inverter, transducer, home appliance.
► Advantages ( Common mode choke core ) :
● High Bs , high μ -- Easy to design , reduce core geometry effectively ● Good frequency flexibility -- Better controlling to the noise in different frequencies ● Low magnetostriction coefficient -- Low noise ● Excellent impedance character -- EMC can guarantee 10000 permeability when resist 80A/M under current bias
● Excellent temperature stability -- Working temperature from -55℃ to 130℃ for a long time
► Curve ( Common mode choke core ) :
• Magnetic hysteresis loop • Permeability characteristics under DC bias
• Frequency response of permeability • μ VS temperature
► Application ( Common mode choke core ) :
Wenergy developed advanced higher property Nano-crystalline common mode choke cores as solution for EMC common mode choke cores requirement, and were applied to the EMC of switch power modules, UPS power supply, communication power supply, inverter, transducer, home appliance.
