PCB transformers are transformers designed for direct mounting on printed circuit boards (PCBs), providing a compact and integrated solution for power conversion and isolation. These transformers are typically used in low to moderate power applications and are found in a wide range of electronic devices, from consumer electronics to industrial controls. PCB transformers are designed to fit within the layout of a PCB, making them ideal for applications where space is limited, and a high degree of integration is required. These transformers can serve various purposes, including voltage step-up, step-down, and isolation. PCB transformers are often used in low-voltage applications, such as signal isolation and low-power DC-DC converters. They are typically designed with surface-mount technology (SMT) or through-hole mounting, allowing for easy integration into existing circuit board layouts. The compact nature of PCB transformers makes them ideal for miniaturized electronic devices, where space optimization is crucial. Additionally, these transformers can be customized with various core materials and winding configurations to meet specific application requirements, providing flexibility in design and performance.
