Details
The integrated inductance consists of a matrix and a winding body. The matrix is made by embedding the winding body into the metal magnetic powder. The SMD pin is directly formed on the surface of the matrix as the lead pin of the winding body, which has higher inductance and smaller leakage inductance than the traditional inductor. Designed for the structure of the inductance patch, it will not damage the inductance and improve the production efficiency. It is commonly used for DC-to-DC rectification applications on power lines in power supplies, personal computers, and other handheld electronic devices.
The advantages of integrated forming inductor: 1, surface attached high-power inductor, miniaturization, high quality, high energy storage, small ground resistance, more space saving, more power saving; 2, various models and sizes. Operating temperature between -40~ 125°; 3, in the case of the same size, the current of the integrated inductor is about 30% higher than that of the traditional power inductor; 4, the use of magnetic glue structure, greatly reduce the buzz; 5, the metallized electrode is welded on the ferrite core, which has strong resistance to vibration and impact and durability. Closed magnetic circuit structure design, less magnetic leakage, strong EMI resistance; 6, the application range is also very wide. Examples include LED lighting, smartphones, flat screen TVS, laptops, desktop computer servers, graphics cards, and personal navigation systems.
After comparison, we will find that the shield inductor is more often used as a protector, like the shield inside the spear and shield. The integrated inductor is like an "all-powerful warrior" that plays a role in different electronic devices.
