The ETD39 Transformer Vertical Bobbin (16 Pin) is a popular choice for use in SMPS (Switched Mode Power Supply) circuits, designed specifically for efficient power transfer with a balance between size and performance. Below is a detailed description of its features and specifications.

Features:

• Core Type: ETD39
• Pin Count: 16 pins (dual row configuration)
• Bobbin Type: Vertical mounting for space-saving in PCB layouts
• Material: High-quality plastic, often flame-retardant (UL94-V0) for safety
• Applications: Ideal for use in power transformers, specifically in high-frequency applications like SMPS, converters, inverters, and more
• Compatibility: Suited for ETD39 cores which are known for their high energy efficiency in power conversion applications
• Winding Slots: The design supports multiple windings, making it suitable for transformers with complex winding configurations

Specifications:

• Pin Pitch: Standard pitch of approximately 5 mm (depending on the manufacturer)
• Dimensions: Typically matches the standard ETD39 core size with a window area optimized for winding
• Max Winding Turns: Supports high-density windings due to the large window area
• Mounting: Vertical bobbin with through-hole pins designed for PCB mounting
