Product Description
Stable Efficient PQ3535 High Frequency Transformer for LLC Power Converter
High-Power Magnetic Excellence
The PQ3535 Series High-Frequency Transformer stands as a premier solution for high-density power electronics, specifically engineered to bridge the gap between mid-range power delivery and large-scale industrial energy conversion. The "PQ" (Power Quality) geometry offers an optimized balance between core volume, surface area for heat dissipation, and a circular center leg that maximizes winding efficiency.
Strategic Selling Points
- Optimized Power-to-Size Ratio: Larger winding window and effective core area compared to traditional EE or EI cores of similar dimensions
- Superior EMI Containment: Semi-closed core geometry acts as a natural magnetic shield, reducing radiated electromagnetic interference
- LLC Resonant Topology Optimization: Engineered for resonant tank circuits with precise leakage inductance and high-quality factor
- High-Grade Mn-Zn Ferrite Core: Premium low-loss ferrite materials maintaining high saturation flux density at temperatures exceeding 100°C
- Professional Insulation System: Multi-layer high-temperature tapes and reinforced insulation leads with dielectric isolation up to 4500V AC
- Advanced Thermal Dissipation: Circular center leg and open-sided bobbin structure facilitate natural air convection

Engineering Insight
The Mn-Zn Ferrite Core Selection ensures the transformer exhibits a flat power loss curve across a wide temperature range. In high-efficiency LLC resonant converters, the Leakage Inductance is a critical circuit parameter, allowing the transformer to act as the resonant inductor itself, reducing total component count. The Dielectric Strength of up to 4500V makes this transformer suitable for stringent medical and industrial safety environments.
Advanced Manufacturing Advantages
PQ Geometry Performance
The circular center leg allows copper wire to follow a natural path with the shortest possible length per turn, reducing DC resistance and minimizing copper losses for significantly higher efficiency and cooler operation.
Precision Winding Architecture
Multi-strand Litz wire or high-insulation secondary leads combat Skin Effect and Proximity Effect at high frequencies. CNC multi-axis winding machines ensure consistent tension and minimized parasitic capacitance for stable operation above 100kHz.
Resin Impregnation Process
Vacuum varnish cycle replaces air pockets with dielectric resin, creating a moisture-proof, vibration-resistant unit that eliminates audible noise from magnetostriction during load shifts.
Automated Quality Verification
High-resolution cameras verify bobbin integrity and pin alignment, followed by full electrical sweep testing under full-load conditions to ensure consistent performance and reduce total cost of ownership.
Industry Applications
Industrial Automation
Primary choice for 300W-450W industrial DC-DC converters, PLC rack supplies, and DIN-rail mount rectifiers. Robust isolation and thermal stability ensure stable power in harsh industrial environments with electrical surges and high ambient heat.
Medical Device & Imaging
Prized for high dielectric isolation (4500V AC) and low EMI signature. Enables compact, bedside medical units that are safe and lightweight while preserving accuracy of delicate analog physiological sensors.
Telecommunications & Computing
Supports high-efficiency AC-DC converters for 5G base stations and data centers. Low core loss at high frequencies contributes to improved Power Usage Effectiveness (PUE) ratios for energy cost reduction.
Renewable Energy & Smart Grid
Provides stable power for solar micro-inverters, battery management systems, and EV charging station modules. Moisture-proof encapsulation and high thermal mass ensure reliability in extreme outdoor conditions.
