PQ type high-frequency transformerDetailed product description：

The magnetic core of PQ type high-frequency transformer is a ferrite core designed to meet the requirements of new switching power supplies. Its shape can meet the requirements of reducing copper and iron losses in switching power supply transformers operating at high frequencies, as well as the temperature rise requirements of switching power supplies; Its circular center column makes winding easier, increases the capacity of the wire package, and the lead end of the skeleton makes product installation very reliable, suitable for switch power supplies and blocking coils. The commonly used models of PQ transformers include PQ2020, PQ2620, PQ3220, PQ3230, PQ3535, PQ4040, PQ5050, etc.

The following table lists the external dimensions and output power of some products.
