Product Overview

Engineered for Excellence

Planar transformers combine low-profile architecture, tight magnetic control, and repeatable PCB-based winding structures to achieve outstanding electrical performance. The optimized geometry enables minimal leakage inductance, reduced copper losses, and excellent heat spreading—ideal for high-frequency SMPS and isolated DC-DC converter topologies.

Each unit is built to meet stringent global reliability standards and is fully customizable to match your power architecture, EMI goals, and thermal envelope.
