• Core Shape: PQ (Power Quality) core, which offers a balanced design with a large window area for windings while maintaining a compact outer profile
• Material: Ferrite, typically made from MnZn (Manganese-Zinc) ferrite materials, designed for high-frequency operation
• Applications: Optimized for high-frequency transformers, such as those used in SMPS, power inverters, and DC-DC converters
• Magnetic Efficiency: The PQ core shape is designed to minimize core losses at high frequencies, ensuring better performance in power conversion systems
• Reduced Copper Loss: The core's design allows for a shorter winding length, minimizing the resistance in the windings and reducing copper losses

Specifications:

• Core Size: The PQ2625 core refers to its specific size, offering a good balance between compactness and enough winding space for high-power applications
  • Outer Diameter: ~26 mm
  • Height: ~25 mm
• Core Material Permeability: Typically available in different permeability grades (µ), ranging from 2500 µ to 10000 µ, depending on the specific ferrite material and application needs
• Saturation Flux Density (Bsat): Ferrite materials generally have a saturation flux density in the range of 300 mT to 500 mT, depending on the material and temperature
• Operating Frequency: Optimized for high-frequency operation, typically between 50 kHz and 500 kHz, depending on the specific application and core material
• Core Loss: Ferrite cores like the PQ2625 are designed to have low core loss at high frequencies, making them ideal for efficient high-frequency transformers
