aHR0cDovL2ZyZWVzaGlwLmNvLmtyThe magnetic ring is made of 125 models with an outer diameter of 33mm, an inner diameter of 19.9mm, a height of 10.7mm, and a magnetic permeability.
The 77548A7 series is selected as the iron-silicon-aluminum magnetic ring inductor, which has the characteristics of high current and strong anti-saturation, low temperature rise in continuous operation at full current, gentle DC bias, and small high-frequency magnetic loss.
It is very suitable for SPWM inverter output filter inductors, power factor correction circuits (PFC inductors), DC/DC converter inductors, and grid-connected inverter filter inductors.
In view of the fact that some customers say that there is a problem with the parameter identification, it is hereby remarked that the inductances marked above are the exact values tested by the bridge, and the current values are the rated current values calculated according to the wire diameter. However, the inductance is linear. According to the increase of the current, the inductance is reduced. The inductance marked above is the no-load value. Please contact the seller to customize the inductance and current of the load value. thanks

Introduction to the selection of magnetic core materials: Because the loss and anti-saturation performance of the magnetic powder core material are better than those of the iron powder core (commonly known as: yellow and white ring magnetic ring), and the iron powder core (yellow and white ring) generally can only work at medium and low frequencies (usually 5kHz). below, and the loss is large). Therefore, the magnetic ring inductors designed by our shop are all made of FeSiAl, high magnetic flux or MPP materials (international magnetic core brand CSC or Magnetics). The comprehensive cost performance of the inductors wound with FeSiAl magnetic cores is high; the inductances wound with high flux magnetic cores are small in size, but the price is higher; the inductances wound with MPP magnetic cores are second in volume and low in loss (FeSiAl, high The loss of magnetic flux is also relatively small), but it is expensive. All three materials can operate at harmonic frequencies up to 500kHz.
