RIGIR has released a new class of square flat wire common mode inductors: SQ30V-22-001. The common mode inductor uses 1.0*2.0 flat wire. The cross section of the wire can be used 100%, which can replace the T31 size magnetic ring. Inductance, the winding space is 30% smaller than the circular line occupancy. Excellent high-frequency characteristics, at 150KHZ, 200KHZ, the inductance attenuation is less than 10%, 20%. In the closed case, there is no air-cooled and no-cool, and it can pass 10A (MAX) power supply. Suitable for 1000W-2000W high power supply, easy to solve 150K-300K frequency EMC.
In this new product, the high-precision flat wire uses only one layer, effectively avoiding the effect of interlayer proximity, and at the same time effectively avoiding the effect of the skin effect in the high frequency band. The flat wire single layer winding can evenly disperse the electric field and reduce the influence of distributed capacitance.
