ETD 29 is a type of ferrite core transformer,power pulse transformer ,high voltage transformer , electronic transformer ,high frequency flyback transformer ,commonly used in electronic devices and power supplies. It is designed to convert high voltage AC power to low voltage AC power, typically used for powering electronic circuits and components. The "ETD" in ETD 29 stands for "Economical Transformer Design" and refers to the specific design standards and dimensions of the transformer. The number "29" indicates the core size and shape of the transformer, with ETD 29 being a specific size and shape of the transformer core. ETD 29 electronic power transformers are typically used in applications where space is limited and high efficiency is required. They are commonly found in power supplies for LED lighting, audio amplifiers, and other electronic devices. These transformers are designed to provide a stable and reliable power source for electronic circuits, while also minimizing energy loss and heat generation. Overall, ETD 29 electronic transformers are an important component in many electronic devices and power supplies, providing the necessary voltage conversion and power distribution for efficient and reliable operation. The term "ETD 29" refers to a specific size and shape of ferrite core used in transformers. The "ETD" stands for "E" (meaning the core shape is E-shaped), "T" (meaning the core is made of ferrite material), and "D" (indicating the dimensions of the core). The number "29" represents the specific dimensions of the core,
