YZ4359-POT40-01

650W AI Server High Frequency Transformer This product is a 650W high-frequency transformer specifically designed for AI server and high-performance computing power supplies. Featuring a POT40 ferrite core and operating at 80kHz, it efficiently converts a 400–440V DC input into isolated low-voltage outputs for GPU or CPU core power delivery. With a 40:1:1 turns ratio and primary inductance of 200µH ±7%, the transformer achieves a typical leakage inductance as low as 6.0µH, making it well‑suited for LLC resonant and phase‑shifted full‑bridge topologies that demand high efficiency and soft‑switching operation. The transformer provides 3000Vac reinforced isolation (primary‑to‑secondary and primary‑to‑core), Class B (130°C) insulation, and is vacuum impregnated to ensure long‑term reliability in demanding server environments. Its compact POT40 form factor supports high‑density power module integration. Ideal for AI accelerators, GPU servers, DC‑DC converters, and telecom rectifiers, this product delivers outstanding performance and reliability for next‑generation computing infrastructure.
