Product Description

  Our ETD Series High-Frequency Switch Mode Transformer is engineered for superior performance and reliability in demanding power supply applications. Featuring a robust horizontal double bobbin (ETD) core structure, this transformer is ideal for SMPS, UPS, inverters, and industrial power systems. Manufactured with precision using high-grade materials, it ensures low loss, high efficiency, and excellent thermal stability. Whether you need a standard model or a fully customized solution, our ETD transformer is designed to meet your specific voltage, power, and safety requirements, providing stable power conversion for your critical equipment. Optimized Core Design for High Efficiency : Adopts high-purity Mn-Zn ferrite cores (high permeability at high frequencies) and oxygen-free copper windings (low resistance), extending product lifespan to over 10,000 hours Horizontal Dual-Slot Structure: Horizontal dual-slot design saves 30% installation space compared to vertical transformers. Reinforced bobbin ensures easy winding and stable assembly, fitting compact power supply enclosures.
  High-Efficiency & Low-Loss Performance :  Boasts ≥95% conversion efficiency and low power loss, reducing energy waste for long-term operation. Low leakage inductance (≤100μH) minimizes EMI interference, ideal for precision equipment. Wide-Temperature Stable Operation :  Operates reliably in -40℃ (low-temperature startup) to +125℃ (high-temperature load) environments, with Class H insulation (180℃) preventing overheating damage.
 
 
Flexible Customization: Offers customization for rated power (30W~6000W), output voltage (12V~48V), lead length (100mm~500mm), and pin type (PCB mount/terminal), with 7-day sample delivery.
 
 
Comprehensive International Compliance: Complies with UL 60950-1, CE EN 61558, and RoHS 2.0 standards, meeting safety and environmental requirements for global markets (Europe, North America, Southeast Asia).
