Resonant Transformers – Preferred sizes

  • Resonant Transformers for LLC or LCC converters, with integrated inductance, preferred sizes.
  • Suited for converters based on chips produced by ST Microelectronics, Fairchild, Texas Instruments, ON Semiconductor, Motorola, NXP, Power Integrations, Infineon, International Rectifier and many others.
  • Operating frequency 40kHz to 1000kHz.
  • High creepage/clearance/DTI for reinforced insulation according to EN61558, EN60950, etc.
  • UL Recognized Component Mark on standard products, available on request on custom products.
