Product Description
Customized PQ26 PQ32 High Frequency Transformer Low Profile Ferrite Core Switching Power Transformer for LED Driver and 5G Telecom
Product Introduction
The PQ Series (Power Quality) high frequency transformer is a premier magnetic solution specifically engineered for high-density switching mode power supplies (SMPS). Designed with an optimized core geometry that balances volume, surface area, and winding space, the PQ series is widely regarded by power engineers as the "benchmark" for high-performance industrial power conversion. It is the ideal candidate for designs requiring a compact footprint without sacrificing thermal stability or electrical efficiency.

Product Features
- Optimized Core Geometry: The PQ core features a unique "squat" circular center post design that maximizes the cross-sectional area (Ae) while providing a shorter mean length per turn (MLT).
- High Frequency Versatility: Specifically optimized for stable operation between 50kHz and 500kHz, making it perfectly compatible with modern high-speed switching topologies like LLC Resonant and Phase-Shifted Full Bridge.
- Standardized Modular Design: Available in a full range of sizes (PQ20, PQ26, PQ32, PQ35, PQ40, PQ50) with standardized bobbins, facilitating rapid prototyping and seamless mass production.
- Premium Material Grade: Constructed using high-permeability, low-loss ferrite materials (equivalent to PC44, PC95, or DMR95) to ensure high saturation flux density even at elevated temperatures.
Technical FAQs
Q: Why does the PQ core's circular center post offer a significant DCR advantage over traditional square-post EE cores?
A: The circular post of the PQ core provides a shorter perimeter for the same cross-sectional area compared to a square post. This leads to a shorter Mean Length per Turn (MLT). By using less copper wire to achieve the same number of turns, DC Resistance (DCR) and copper losses are reduced by 10-15%. This improvement is critical for achieving 80 PLUS Titanium efficiency ratings in high-current industrial power supplies.
Q: How does the "squat" physical profile of the PQ series improve thermal management compared to taller EE transformers?
A: Thermal management is all about surface-area-to-volume ratio. The PQ core has a relatively large surface area compared to its volume. Its low-profile, wider shape allows for much better natural convection and provides a larger contact surface for thermal interface materials or cold plates. Additionally, the outer core legs provide magnetic shielding, which contains stray flux and radiated noise, simplifying EMC compliance for sensitive industrial electronics.
Product Applications
The PQ series is the cornerstone of high-reliability power systems across various sectors:
- Industrial Automation: Powering PLCs, motor drives, and heavy-duty robotic controllers
- Renewable Energy: Main power conversion stages in commercial solar inverters and energy storage systems
- EV Infrastructure: DC-DC conversion in high-wattage on-board chargers (OBC) and fast-charging piles
- Telecommunications: Ultra-efficient power modules for 5G base stations and data center server racks
Product Advantages
The primary competitive advantage of the PQ series lies in its Thermal Superiority. The wide outer legs of the PQ core partially enclose the windings, acting as a natural heat sink while providing an inherent shielding effect against electromagnetic interference (EMI). Furthermore, the wide core window allows for the use of thicker Litz wire or copper foil, which drastically reduces AC resistance and prevents localized hot spots. This structural stability ensures a long operational lifecycle even in 24/7 mission-critical environments.
