1. Compact & Flat Design
Low-profile ER cores (e.g., ER9.5/ER11) save PCB space (<10mm height).
2. High Flux Density
Ferrite cores (e.g., 3C90) support 300mT at 100kHz with <2% distortion.
3. Low Winding Loss
Wide winding window reduces copper loss (Rac/Rdc <1.2 at 1MHz).
4. Thermal Stability
Open structure enhances cooling (power density: 0.5–1.5W/cm³).
5. Cost-Effective
Standardized bobbins simplify mass production (30% cheaper than planar designs).
Consumer Electronics: USB-PD adapters (20–65W).
IoT Devices: Wireless charger Tx/Rx coils (Qi standard).
Automotive: LED driver modules (AEC-Q200 compliant).
Industrial: Sensor isolation (CAN bus).
YET focus in custom development and low volume methodology allow us to be one of the most flexible and agile manufacturers in the industry.
