Description

The UF86A U-shape ferrite core set is designed for custom high-frequency magnetic components such as inverter transformers, RF chokes, isolation transformers, switching power supply transformers, and experimental power electronics projects.

This set includes 2 U-shaped ferrite core pieces, allowing the user to form a closed magnetic path when paired together. The large core size makes it suitable for higher-power projects where a standard small ferrite core may not provide enough winding space or magnetic cross-section.

The UF86A core is made from MnZn PC40 ferrite material, commonly used in high-frequency transformer and power conversion applications. It is suitable for experienced builders designing custom transformers for inverter circuits, resonant converters, DC-DC converters, RF choke assemblies, and other switching power systems.

Typical Applications

• High-frequency inverter transformers
• Isolated DC-DC converter transformers
• Switching power supply transformer builds
• RF choke and ferrite bead applications
• Induction heating and resonant power circuits
• Custom transformer and inductor experiments
• Power electronics research and prototyping

Important Notes

• Design knowledge required: This is a ferrite core set only. Wire, bobbin, clamps, spacers, and mounting hardware are not included unless stated separately.
• Core gap depends on assembly: Final magnetic performance depends on winding design, air gap, clamping method, operating frequency, and circuit topology.
• Handle with care: Ferrite material is hard but brittle and may crack if dropped or clamped unevenly.
• Verify before use: Always confirm the core dimensions and suitability for your transformer or choke design before building high-power circuits.

Tip: For inverter and resonant converter projects, choose the core size based on target power, switching frequency, turns ratio, flux density, winding window, and cooling requirements.
