Product Description:
EC/ER type transformers are basic ferrite core, they are widely used in switching power supply and a variety of electronic lines, oscillation There are full-bridge,half-bridge, single-ended, resonant, push-pull lines, etc., with excellent material characteristics, suitable for typical transformer structures The cylindrical center column of the EC/ER core makes it easier to wind, and increases the cross-sectional area of the winding, which can increase the output power, and is suitable for each Kind of switching power supply transformer and choke coil. The EC type transformer model to have EC2820 EC2828, EC2834, EC3535, EC3542, EC4042,EC4950, EC5345, EC70, etc.
The following table lists the dimensions and output power of some products. With the different characteristics of magnetic materials and operating frequencies The maximum output power will vary, and the data in the table is for reference only.
Test conditions 1KHz/1V, withstand voltage AC2000V, insulation resistance :DC500V≥200MΩ
