AI Overview
(7 pins) or
(8 pins) configurations made from UL 94V-0 rated phenolic material for high heat resistance. These bobbins enable low-profile, high-power designs often used in power supplies.
Key Features and Specifications:
- Material: Phenolic (high-performance polymer, UL94V-0)
- Configuration: Horizontal, 1-section, usually 2+5 or 4+4 pins
- Dimensions: Small, compact, typically for EFD12 ferrite cores
- Pin Pitch: Approx. 2.5mm–3.75mm with 12.3mm parallel distance (varies by model)
- Application: High-frequency transformers, switching power supplies
- Accessories: Generally used with SUS301 iron clips
Commonly Available Types:
- 2+5 Pin EFD12: Horizontal, 1 section (often found on Mycoiltech)
- 4+4 Pin EFD12: SMD or Through-hole, commonly used in compact designs (examples found at Fuantronics)
These bobbins are suitable for high-density, low-profile electronics, particularly whenpaired with EFD12 power ferrite cores.
