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
