PQ Transformer
PQ type high frequency transformer cores in order to meet the requirements of the new switching power supply designed ferrite core, its shape can meet to work in high-frequency switching power supply transformer to reduce copper loss and iron loss requirements, the same switching power supply can also be adapted to the temperature rise requirements; its winding round the center column to make it easier, line pack capacity expansion, the lead end of the product installation skeleton very reliable and suitable for switching power supplies and choke coils. PQ type transformers commonly used models PQ2020, PQ2620, PQ3220, PQ3230, PQ3535, PQ4040, PQ5050 so on.
The following table lists some of the products dimensions and output power.
With different magnetic properties and the operating frequency, maximum output power will vary, the data sheet for reference only.
Test conditions 1KHz/1V, pressure AC2000V, insulation resistance: DC500V ≥ 200MΩ.
