ETD29 Transformer Horizontal Bobbin 12 Pin

The ETD29 Transformer Horizontal Bobbin (12 Pin) is another widely used bobbin type in transformer designs for applications such as Switched Mode Power Supplies (SMPS) and other high-frequency power conversion systems. Here’s a breakdown of its features and specifications.

Features:

• Core Type: ETD29
• Pin Count: 12 pins (dual row configuration)
• Bobbin Type: Horizontal mounting, providing a lower profile on the PCB for space-constrained designs
• Material: High-quality plastic (often UL94-V0 rated) for heat and flame resistance
• Applications: Ideal for power transformers in SMPS circuits, inverters, and converters, where compact, horizontal PCB layouts are preferred
• Winding Support: Multiple winding slots designed to accommodate different primary and secondary windings

Specifications:

• Pin Pitch: Typically around 5 mm (varies by manufacturer), ensuring compatibility with standard PCB layouts
• Dimensions: Standard ETD29 core size, with a bobbin window optimized for winding and high energy efficiency
• Winding Area: Adequate for high-density windings, which is essential for high-frequency transformers
• Mounting: Horizontal bobbin, designed for through-hole mounting on PCBs, ensuring a low-profile setup
• Compatibility: Designed for use with ETD29 cores, which are known for their compact size and good performance in high-frequency applications
