DONGGUAN, China – September 9, 2026 – The era of bulky power supplies is officially over. As the global industrial sector transitions to Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductors, the pressure on magnetic components to operate at higher frequencies has intensified. Today, Chipsen Electronics Technology unveiled its "Hyper-Freq" series, a collection of transformers and inductors engineered to operate reliably at frequencies exceeding 1MHz, effectively shrinking power module sizes by an additional 40%.
Traditional silicon-based power systems are limited by switching speeds and heat. Wide-bandgap semiconductors (GaN/SiC) can switch much faster, but only if the transformer can keep up. Chipsen’s new EPC and EFD Series transformers utilize a proprietary high-frequency ferrite formula that maintains extremely low core loss even at megahertz levels.
“We aren't just making components smaller; we are making them smarter," stated Chipsen’s Director of Innovation. “By matching our magnetics to the latest GaN FETs, we’re enabling 100W chargers the size of a matchbox and industrial motor drives that fit into the palm of a hand."
Beyond speed, Chipsen is setting new benchmarks in human safety. The newly launched Medical-Grade Isolation Series is designed for life-support systems and high-precision diagnostic imaging. These components feature reinforced insulation that exceeds the latest IEC 60601-1 (2 x MOPP) requirements, ensuring absolute patient safety even in the event of a catastrophic circuit failure.
Q: Why do some high-frequency transformers produce an audible "buzzing" or "whining" sound? A: This is usually due to magnetostriction—where the core material physically changes shape slightly under a magnetic field. Chipsen solves this through Vacuum Pressure Impregnation (VPI), using specialized epoxy resins that lock the core and windings in place, silencing audible noise even under full load.
Q: Is SMD (Surface Mount) always better than Through-Hole for industrial robotics? A: Not necessarily. While SMD (like our ER and EQ SMD series) is great for automated assembly and space-saving, Through-Hole components still offer superior mechanical strength in high-vibration environments, such as robotic arms or heavy machinery. We offer "Hybrid" designs to give you the best of both worlds.
| Feature | Standard Ferrite Core | Chipsen Nanocrystalline | Impact on Design |
|---|---|---|---|
| Switching Frequency | Up to 300 kHz | 1 MHz - 3 MHz | Allows for much smaller capacitors/filters |
| Operating Temp | < 100°C (Stable) | Up to 155°C (Stable) | Ideal for under-the-hood automotive use |
| Flux Density (Bs) | ~0.4 Tesla | ~1.2 Tesla | Prevents core saturation in high-surge peaks |
| Footprint Size | 100% (Baseline) | 60% (Compact) | Significantly reduces total PCB real estate |
Quality at this scale cannot be achieved by hand. Chipsen has recently integrated AI-driven optical inspection (AOI) across its primary production lines. Every single T22 Common Mode Choke and EF20 Transformer undergoes a 360-degree high-speed visual audit and automated pulse testing before leaving the factory. This "Zero-Defect" initiative has reduced RMA rates to an industry-leading <50 PPM (parts per million).
From the 5G base stations atop mountains to the high-speed rail systems crossing continents, Chipsen magnetics are the silent partners in global connectivity. By focusing on High-Q factors and Stable Inductance, we ensure that data signals remain crisp and power delivery remains unwavering, regardless of environmental interference.
