Bourns® planar transformers feature a compact, low-profile design optimized for high-density power conversion applications such as automotive On-Board Chargers (OBCs), DC-DC converters, and industrial power supplies. Unlike conventional wire-wound transformers, Bourns planar transformers utilize flat copper windings layered in a PCB or laminated structure, enabling a significantly reduced form factor and improved thermal performance.
This unique winding geometry minimizes leakage inductance and AC losses, enabling high-frequency operation with superior power efficiency. The precise alignment of layers also allows for better control of parasitic elements, reducing EMI and improving signal integrity in high-speed switching environments.
Bourns planar transformers are designed to support high isolation voltages and are qualified to AEC-Q200 standards, ensuring robust performance under automotive-grade temperature, vibration, and thermal stress conditions. The core and winding designs are optimized using advanced simulation tools to tailor each transformer to specific topologies such as LLC, Flyback, or Full-Bridge.
For further design flexibility, Bourns offers both standard and custom planar transformer solutions, allowing customers to specify turns ratios, insulation requirements, and mechanical form factors. Additionally, their design enables efficient heat dissipation, supporting higher power levels without compromising reliability.
With this combination of high efficiency, miniaturization, and reliability, Bourns planar transformers deliver a next-generation magnetics solution for today's compact, high-performance power architectures.
