TF-EP13C-5526 High Frequency Transformer: Core Technology Breakdown
The TF-EP13C-5526 exemplifies OSWELL’s expertise in high-frequency magnetic design. Engineered for 100 kHz–1 MHz switching power applications, this transformer utilizes specialized ferrite core geometry to achieve 98% efficiency while solving critical EMI/thermal challenges in modern power systems.
Core Technical Advantages
Low-Core-Loss Material: N97 ferrite formulation reduces hysteresis losses by 40% vs. conventional cores at 500 kHz
Optimized Winding Technique:
Triple-insulated foil windings eliminate inter-layer capacitance
Fractional-turn design minimizes proximity effect losses
Vertical/Horizontal Flexibility: Unified mounting points enable both Vertical Type Transformer (for convection cooling) and Horizontal Type Transformer (forced-air) configurations
