PQ Cores,Core Ferrite Manufacturers,Mn-Zn Ferrite Cores,PQ Ferrite Core,Power MnZn ferrite core China Professional Ferrite Core Supplier p PQ CORES Introduce of PQ cores PQ Ferrite Core, one kind of Mn-Zn Ferrite Cores, are designed especially for switched mode power supplies. The design provides an optimized ratio of volume to winding area and surface area. As a result, both maximum inductance and winding area are possible with a minimum core size. The PQ cores thus provide maximum power output with a minimum assembled transformer weight and volume, in addition to taking up a minimum amount of area on the printed circuit board. Assembly with printed circuit bobbins and one piece clamps is simplified. This efficient design provides a more uniform cross-sectional area; thus Power MnZn ferrite core tends to operate with fewer hot spots than with other designs. Advantages of PQ Cores Assemblies As one of specialty Core Ferrite Manufacturers, our PQ Cores posses special advantages as fllows,wide core selection; unique one-piece clamp; minimal wire losses; heavy wire capability; multiple tap capability; consistency and uniformity; compact packaging on PCB easy; low-cost assembly; 12, 14 pin bobbins; easy mounting, etc. Also we have high-tech manufacture than other Core Ferrite Manufacturers. with fewer hot spots than with other designs.
