Company Profile

PCT INDUSTRIES LTD., the world's leading manufacturer of planar transformers and traditional transformers, proudly introduces our breakthrough technology innovation PCT planar transformers.

PCT planar technology introduces new concepts of magnetic components into the world of high frequency and high efficiency switching power supply (SMPS) design.

PCT planar transformers and inductors are significantly different from conventional electromagnetic components because they typically do not use enamelled wires but use copper foil, copper or flat copper coils, and provide interlayer insulation from epoxy, polyester, fiber paper, and the like. The pre-formed copper windings can be twisted or connected in parallel to meet customer requirements, and the transformers can be combined quickly and easily using prefabricated circuit boards or copper-plate designs.

The PCT AC line power transformer uses a special high-insulation patented structure to meet stringent requirements for creepage distances and clearance distances in accordance with UL, IEC, and VDE standards. The sandwich structure greatly improves the coupling of the primary and secondary and significantly reduces the parasitic leakage inductance, which greatly simplifies the power supply design.

The good fixed design greatly improves the accuracy of the calculation, which is impossible to achieve with the traditional winding method. Our catalogue shows the most popular custom transformer and inductor parameters, from T14 to T5000, and there are also some ready-made products to choose from. Our experienced team can design a wide range of products to meet the needs of our customers.
