Our SMPS transformer cores are designed for small switching power transformers. The toroidal cores are intended for high-frequency, low-power (not more than 400W) power conversion power supply transformers.

Features:
♦ High saturation magnetic flux density - reduced volume transformer
♦ High permeability, low coercivity – Greatly improved transformer efficiency, reducing power and excitation coil distribution parameters
♦ Low-loss - to reduce the transformer temperature
♦ Excellent stability - long-term operation at 130 ℃

Applications:
♦ An alternative permalloy and ferrite
♦ Small single-ended, half-bridge, full-bridge or push-pull frequency switching power supply transformer core
♦ DC-DC AC-DC DC-AC converter transformer core
♦ Small power transformer core module
