TDK inductors are divided into three types: lamination processing technology, winding technology (automatic or manual), or thin film technology. TDK realizes the lamination technology of high electrification, high Q and further miniaturization through its unique multilayer circuit board processing technology. By using high- μ The high closed magnetic circuit structure of ferrite particles is a winding technology to reduce RDC value and realize low power consumption. Through the combination of precise pattern formation and metal magnetic materials, the film technology of small low back and high characteristic products is realized. It has a wide range of products and can select the best products suitable for high-frequency circuit, signal circuit, power circuit and other purposes and meet the required characteristics. In addition, there are all kinds of special products for on-board vehicles.
