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.

PQ Cores are built with dimensions that provide an optimized ratio of volume to winding and surface area. They offer maximum power output with a minimum transformer weight and volume. The cores work with only a few hot spots as compared to other designs. They are available in a variety of sizes such as PQ2020, PQ2609, PQ2610, PQ2616, PQ2620, PQ2625, PQ3220, and PQ3230. Common applications of PQ cores are SMPS and power inductors.
Pros
Optimized ratio of volume to the winding area
Max power output with least transformer weight
Few hot spot
Cons
Pressing can be done on a hydraulic press with pneumatic control
Applications
SMPS
Power inductor
