Ferrite PQ Cores
PQ 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 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 cores tend to operate with fewer hot spots than
with other designs.
