The ETD34 Transformer Horizontal Bobbin (12 Pin) is a common component in power electronics, particularly in high-frequency transformer applications like Switched Mode Power Supplies (SMPS), converters, and inverters. Here’s a detailed overview of its features and specifications.
Features:
- Core Type: ETD34
- Pin Count: 12 pins (dual row configuration)
- Bobbin Type: Horizontal mounting for low-profile PCB designs
- Material: Typically constructed from durable plastic, often rated for flame retardancy (UL94-V0)
- Applications: Suited for SMPS, inverters, converters, and other high-frequency transformers, where compact and efficient designs are required
- Winding Support: Multiple winding slots, allowing for separate primary and secondary windings with good isolation and heat management
Specifications:
- Pin Pitch: Standard pin spacing (around 5 mm, may vary slightly by manufacturer)
- Dimensions: Designed for the ETD34 core size, offering a good balance between winding area and compactness
- Winding Area: Generous winding window to support high-density windings, critical for efficient high-frequency operation
- Mounting: Horizontal bobbin for through-hole PCB mounting, providing a low-profile transformer design
- Thermal Resistance: Often rated to handle the heat generated by high-frequency switching operations
- Compatibility: Works with ETD34 cores, which are optimized for high power density and energy efficiency in transformer designs
