Core advantages of PQ transformer
1. Copper foil winding process significantly reduces high-frequency skin effect, resulting in lower coil loss and lower temperature rise
2. The adhesive layer has good thermal conductivity, quickly dissipating coil heat and improving overall stability of the machine
3. Reasonable magnetic circuit design, low magnetic leakage, and reduced EMI interference to surrounding circuits
4. Low DCR DC resistance reduces active power loss in the circuit and improves the overall efficiency of the power supply
5. The adhesive layer has good thermal conductivity and can quickly dissipate coil heat, improving the stability of the entire machin

FAQ
Q: What is the difference between PQ4040 copper foil PFC inductor and PQ4040 high-frequency transformer?
A: PFC inductor is a single winding used for energy storage, boosting, and resonance; High frequency transformers have multiple windings that achieve voltage isolation and transformation. The two have different functions but similar appearances and cannot be replaced with each other.

Q: What is the maximum saturation current that PQ4040 copper foil inductor can achieve?
A: The saturation current can be customized, with a conventional range of 15~40A, depending on the thickness of the copper foil and the design of the magnetic core air gap. It can be designed according to the circuit parameters of your project.
Q: What devices is this PQ4040 inductor suitable for?
A: New energy charging piles, energy storage inverters, photovoltaic inverters, high-power industrial power supplies, high-power PFC power supplies, high-power UPS.
Q: Can the terminals be changed to pin type?
A: PQ4040 high-power version defaults to copper high current terminals; If the current demand is low, it can be evaluated to switch to a plug-in solution.
Q: What is the function of epoxy sealing?
A: Fixed coils eliminate electromagnetic noise, enhance insulation and voltage resistance, conduct heat and dissipate heat, while also being moisture-proof and earthquake resistant, protecting windings from environmental influences.
