Brief: Looking for a straightforward way to solve common power supply challenges? This video provides a detailed walkthrough of the EPC13 high-frequency transformer, showcasing how its compact design and advanced engineering redefine charging efficiency and power density for modern AC-DC adapters and USB chargers.
Related Product Features:
  • High efficiency and low loss design using premium ferrite cores and optimized winding to minimize core and copper losses.
  • Compact EPC13 footprint delivers excellent power density and transfer capability for space-constrained applications.
  • Automated manufacturing ensures excellent consistency with tight tolerances on key electrical parameters.
  • Designed winding structure suppresses high-frequency noise for a low EMI profile in sensitive circuits.
  • Robust insulation system with Class B (130°C) or higher materials and triple-insulated wire options for safety.
  • Mechanical stability enhanced through potting or vacuum varnish impregnation for improved durability.
  • Customizable electrical parameters including primary inductance, turns ratio, and winding configuration.
  • Available in various mounting styles and designed to meet international safety standards like UL, VDE, and IEC.
Faqs:
  • What are the primary applications for the EPC13 high-frequency transformer?
    The EPC13 transformer is ideal for AC-DC adapters, USB chargers, LED lighting drivers, auxiliary power for home appliances and industrial controls, isolated DC-DC converters in networking/telecom equipment, and low-power switch-mode power supplies (SMPS).
  • How does the EPC13 transformer ensure electrical isolation and safety?
    It provides safe electrical isolation through magnetic coupling instead of direct electrical connection, preventing dangerous high voltage from reaching accessible parts and blocking noise and interference to protect sensitive circuits.
  • What customization options are available for the EPC13 transformer?
    You can customize primary inductance, turns ratio, winding configuration, mounting styles (vertical, horizontal, SMD), and request custom labeling, tape color, and packaging, all while meeting international safety standards.
