Nanocrystalline Cores for EMC Filter Common Mode Inductor (Choke)

Nanocrystalline Cores for EMC Filter Common Mode Inductor (Choke)
Product name:Nanocrystalline Cores for EMC Filter Common Mode Inductor (Choke)
Item:261
Details:
Introduce:
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 ease, 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.

Characteristics:

•High initial permeability: 5~20 times higher than ferrite core

• High saturate induction density: 2-3 times higher than ferrite core, not easy be saturated in high current fields

• Excellent temperature stability-with the serving temperature from -55 to 130"C for a long time. The Curie temperature
  is higher. The properties are not changeable easily even in unstable working temperature.

• Good frequency flexibility-better controlling to the noise in different frequencies.

• Higher anti-unbalanced-current: Specially made Nano-crystalline EMC Common Mode Choke Cores can guarantee
  104 permeability when resist 80A/m unbalanced  current bias field.

 


Application:

• Protection for accuralc clcctronic equipment

• Common mode jam filtering for EMI power

• Common filtering in single phase or three phase circuit

· Switching power supply
· Photovoltaic Inverter
· Drive
· EMC filter
· Welder
· Wind power
·electric car
· Cooker
·ups
 

Product Specifications:

 



Note:Welcome other specification and Customer required dimension is available

Feature:
High of Bs, high values ​​of u, having a high resistance saturation capacity, inductance can
effectively reduce the size, shown as a common mode inductor core static hysteresis loop 1;
· Excellent frequency characteristics, as shown in Figure 3 the core permeability versus frequency curve;
Stable temperature characteristics of the core magnetic permeability change with temperature
change curve shown in Figure 4;
Small magnetostrictive coefficient, low noise;
