The ETD44 Transformer Horizontal Bobbin (16 Pin) is a robust component typically used in high-power and high-frequency applications, such as Switched Mode Power Supplies (SMPS), inverters, and converters. It supports larger power capacities due to its size and pin count. Here’s a detailed description of its features and specifications.

Features:

• Core Type: ETD44
• Pin Count: 16 pins (dual row configuration)
• Bobbin Type: Horizontal mounting, ideal for designs that require a low profile on the PCB
• Material: Constructed from high-quality, heat-resistant plastic, often with a UL94-V0 flame retardant rating
• Applications: Designed for use in high-frequency transformers for SMPS, inverters, and converters, where high efficiency and compact design are critical
• Winding Capability: The bobbin is designed to accommodate multiple windings, making it suitable for transformers with complex primary and secondary winding arrangements

Specifications:

• Pin Pitch: Standard 5 mm spacing between pins (varies slightly depending on the manufacturer)
• Dimensions: Standard ETD44 core size with a wide window area for winding, optimized for high power density
• Winding Area: Large window size to support high-turn windings and thicker wires, ideal for handling higher power levels and maintaining efficiency in high-frequency applications
• Mounting: Horizontal bobbin, designed for through-hole mounting, offering a low-profile transformer setup on the PCB
• Thermal Management: Good thermal resistance, suitable for managing the heat generated in high-power, high-frequency applications
• Compatibility: Specifically designed for use with ETD44 cores, known for their ability to handle high energy density while maintaining efficiency
