The ETD39/20/13 Ferrite Transformer Cores are designed for high-performance power transformers in applications such as switch-mode power supplies (SMPS), inverters, and other high-frequency power conversion systems. The ETD39 core shape is optimized for easy winding and efficient magnetic performance, minimizing energy losses in high-frequency operations. Supplied as a pair, these cores create a closed magnetic circuit for effective energy transfer.

Features:

• Core Shape: ETD39 core shape allows for efficient magnetic performance and ease of winding, making it ideal for compact transformer designs.
• Material: High-quality ferrite material that provides low core losses, particularly at high frequencies.
• High Magnetic Permeability: Ensures superior magnetic flux control, increasing the efficiency of energy transfer.
• Low Core Losses: Designed to minimize eddy current and hysteresis losses in high-frequency applications.
• Pair Configuration: Comes as a pair (two cores), forming a complete magnetic path when assembled for optimal performance.
