Frequently Asked Questions
What are the primary applications for ETD series switching power transformers?
ETD series transformers are widely used in high-frequency switching power supplies, telecommunications, and industrial automation due to their excellent efficiency and power handling capabilities.
What core material is used in these specifications?
These specifications are based on the high-performance PC40 series ferrite material, which is optimized for low power loss at high frequencies.
What is the standard switching frequency for these designs?
The standard design parameters assume a switching frequency of 100KHz, which is typical for modern forward model power converters.
How does the frame type affect the installation?
The horizontal frame type used in these models allows for a lower profile on the PCB, making them suitable for applications where vertical space is limited.
Can the output power exceed the values listed in the table?
The Maximum Output Power (VA) listed (170-380 VA) is based on the specific design conditions. Actual performance may vary depending on cooling conditions and circuit topology.
Are custom dimensions available for specific PCB layouts?
While ETD-29, 34, and 39 are standard sizes, we offer customization for winding configurations and pin assignments to match your specific electronic requirements.
