Nanocrystalline Core for Common Mode Choke
Due to unique combination of magnetic properties, nanocrystalline cores are widely used in application of common mode choke (CMC). Low cost(iron-based) and large-scale production (rapid solidification technology) make SWFNA being a more competitive solution especially than ferrite in EMC field.
Product Introduction
Due to unique combination of magnetic properties, nanocrystalline cores are widely used in application of common mode choke (CMC). Low cost(iron-based) and large-scale production (rapid solidification technology) make SWFNA being a more competitive solution especially than ferrite in EMC field.
FEATURE
> High permeability
> High saturation
> Low Temperature Dependence
BENEFIT
> Big impedance
> Small dimension
> Wide operating temperature range
HIGH-LIGHT
>> Little Copper Wire Winding Turns << >> Small Distributed Capacitance <<
>> Wide Adjustable Permeability Range << >> High Linear Change of Permeability <<
FREQUENCY RESPONSE
SWFNA nanocrystalline cores has better permeability response to frequency.
The permeability μ 'of SWFNA is significantly higher than normal ferrite (Mn-Zn) in low frequency range and remains above the normal ferrite.
IMPEDANCE
High attenuation means high impedance.
To achieve high impedance, high permeability core material is preferred than increase of turns of copper wires winding. SWFNA nanocrystalline cores has higher permeability of and wider adjustable permeability range on which SWFNA cores make themselves being the prior choice for application of common mode choke.
THERMAL PROPERTITY
In operating temperature range (-55 to 130℃),the saturation flux density of SWFNA cores only change in very few percent (less than 1%), meanwhile normal ferrite (Mn-Zn) cores decline around 40% when temperature above 100℃.
Because of high curie temperature (570℃) of SWFNA, a short-term operation is allowed maximum temperature range of 150~180℃.
TOLERANCE TO INTERFERENCE CURRENT
In electricity network, long motor cable with different capacitance of conductor to earth or short, extremely high and rapidly declining current normally cause medium/high frequency interference current of common mode, unbalanced or low frequency current of leakage.
These common mode currents often exceed the saturation level of choke or core, and choke breaks down
and becomes disable.
Normal ferrite (Mn-Zn) has lower saturation flux density (around 0.4T) and lower sensitivity due to its lower permeability. SWFNA's high saturation flux density (1.23T), wider adjustable permeability range (up to 200,000) and higher permeability frequency response enable SWFNA cores to be saturation-resistant solution.
