High Power Planar Transformer

The fundamental distinction between planar Transformers and traditional transformers lies in their Magnetic Cores and windings. Planar high frequency transformers employ compact E/RM/ferrite cores typically made from high-frequency power ferrite material, delivering ultra-low core loss – a critical feature for High Frequency Current Transformer applications.

Multi-Layer Architecture
The windings are constructed via multi-layer PCB technology, where copper traces are laminated onto planar ferrite cores to create precision magnetic circuits. This High Frequency Transformer optimized design achieves:
· Ultra-low DC resistance (<0.2% primary inductance)
· Leakage inductance meeting high frequency current transformer standards
· Distributed capacitance optimized for resonant circuits

Technical Advantages vs Traditional Transformers
· High current density
· 98%-99% efficiency across operating cycles
· EMI suppression compatible with high frequency current Transformer arrays
· Compact SMD packaging for transformer-intensive systems
· 10KHz-800KHz frequency range exceeding standard transformers
· 4kV insulation validated for high frequency transformer stacks
