The ETD44 9+9 pin horizontal transformer bobbin with PC40 ferrite core is engineered for high-efficiency power conversion in medium to high power switch-mode power supplies (SMPS), inverters, and other high-frequency applications. Its large core area, low core loss material, and optimized winding layout make it ideal for compact yet powerful transformer designs.

Key Features:

• ETD44 Ferrite Core (PC40) – High magnetic performance with low core loss for high-frequency applications
• 9+9 Pin Bobbin – Suitable for multiple winding configurations with enhanced creepage and clearance
• Horizontal Mounting – Provides a lower profile for height-constrained designs
• Flame-Retardant Bobbin – High dielectric strength and temperature-resistant thermoplastic
• Excellent for SMPS Transformers, Inverters, and Flyback Converters
