Excellent quality Drum Core Inductor - Double Slot ETD34 Horizontal High Frequency PCB Mount TV Flyback Transformer 12V – Sanhe
Excellent quality Drum Core Inductor - Double Slot ETD34 Horizontal High Frequency PCB Mount TV Flyback Transformer 12V – Sanhe Detail:
Introduction
SANHE-ETD34 is mainly used for the power supply of laser TV. As power of laser power supply is rather large, it adopts LLC resonance scheme with soft switch in order to lessen loss and improve efficiency. The transformer can provide both main working voltage of the power supply and auxiliary working voltage required by the chip, so as to cooperate with each components to convert digital signal into the corresponding optical information and project required image.

Features
1. ER35 double-slot structure, leakage inductance between the primary and secondary windings is used as the resonant inductance
2. Integral shell is used to isolate the primary from secondary windings to ensure safety distance
3. Peripheral protective tape isolates the transformer from surrounding components
4. Auxiliary winding is placed on the primary side for stable voltage
Advantages
1. The secondary side winding is wound in parallel with two wires for stable voltage output
2. Leakage inductance working as the resonant inductance simplifies the circuit and saves costs
3. Shell and peripheral tape for insulation provides necessary protection for the transformer
4. Good temperature rise and reliability
