PQ CORES
Introduce of PQ cores
PQ Ferrite Core, one kind of Mn-Zn Ferrite Cores, are designed especially for switched mode power supp
design provides an optimized ratio of volume to winding area and surface area. As a result, both maxim
inductance and winding area are possible with a minimum core size. The PQ cores thus provide maximu
output with a minimum assembled transformer weight and volume, in addition to taking up a minimum
of area on the printed circuit board. Assembly with printed circuit bobbins and one piece clamps is simp
This efficient design provides a more uniform cross-sectional area; thus Power MnZn ferrite core tends t
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 c
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; e
mounting, etc. Also we have high-tech manufacture than other Core Ferrite Manufacturers.
