SMT Transformer

Thank to the long history of development in moulded inductor, Crootem provides all series of SMT inductors with high power density, which are the most suitable for high power density module or POL (Point of load) power supply with VRM, VTM and other techniques.

Consultation and Engineering Services:

  1. Design of Transformer
  2. Calculation and Proposal of Specifications

Case Study: Optimized SMT design for power electronics under 30W

  • f = 300 kHz
  • Power = 5W
  • Vi = 18-36V
  • Ii = 4.5A
  • Vo = 5V
  • Io = 1A
  • Flyback Transformer
  • SMT Packaging
