Core advantages of PQ transformer
1.Circular central column, smooth wire winding, high window utilization rate, effectively reduces leakage inductance, reduces switching spikes, and improves the overall efficiency of the power supply.
2. The PQ structure has a certain degree of magnetic shielding effect, resulting in less electromagnetic radiation outward and making it easier to pass the EMC test.
3. The mainstream vertical 6+6PIN pin frame occupies a vertical height, reducing the space occupied by the circuit board on the plane.
4. The magnetic core is locked by metal steel clips; it is compatible with fully automatic winding and automatic tape rolling processes, and the batch consistency of inductance and turns ratio is good.
5. Combined with PC40/PC44 ferrite materials, the working frequency is 20-500kHz, the temperature rise under rated load is good, and it supports long-term continuous operation.

FAQ
Q: What is the common pin configuration for PQ2620?
A: The market standard is a vertical 6+6PIN PCB pin arrangement. Special pin layouts can also be customized according to winding requirements.
A: The market standard is a vertical 6+6PIN PCB pin arrangement. Special pin layouts can also be customized according to winding requirements.
Q: How is the magnetic core of PQ2620 fixed?
A: It is fixed by metal spring steel clips that clamp the two halves of the magnetic core. There is no plastic casing, and the structure is simple, making it suitable for internal assembly in power supplies.
Q: What are the advantages of the PQ2620 cylindrical core?
A: The circular cylindrical winding has smaller bending, higher window utilization, which is conducive to reducing leakage inductance, lowering switching voltage spikes, and improving power conversion efficiency.
Q: How is the EMI performance of PQ2620?
A: The PQ has its own local magnetic shielding built-in, and the external radiation interference is lower. The EMC debugging difficulty of the entire machine is also lower.
Q: What is the normal temperature rise of PQ2620 under rated load?
A: When the heat dissipation conditions are good, the rated load temperature rise is ≤ 45K. When overloaded or with poor heat dissipation, there will be excessive temperature rise, efficiency decline, and howling(noisy sound) phenomena.
