Samsung Electro-Mechanics said on the 14th that it has developed the world’s smallest inductor.
The inductor developed this time is an ultra-miniature product with a size of 0804 (length 0.8mm, width 0.4mm). Compared with the smallest size 1210 (length 1.2mm, width 1.0mm) used in mobile devices in the past, the area is Significantly reduced, the thickness is only 0.65mm. Samsung Electro-Mechanics plans to provide this product to global mobile device companies.
Inductors, as the core parts required for stable transmission of power in batteries to semiconductors, are indispensable parts in smart phones, wearable devices, and electric vehicles. Recently, IT equipment is becoming lighter, thinner and miniaturized. The number of parts installed in multi-function and high-performance products such as 5G communications and multi-function cameras has increased, and the number of internal parts installed controls has decreased. At this time, ultra-micro products are required. In addition, as the performance of parts gets better, the amount of electricity used increases, so inductors that can withstand high currents are required.
The performance of an inductor is generally determined by its raw material magnetic body (a magnetic object) and a coil (copper wire) that can be wound inside. That is to say, in order to improve the performance of the inductor, the characteristics of the magnetic body or the ability to wind more coils in a specific space are required.
Through the material technology accumulated by MLCC and the application of semiconductor and substrate production technology, Samsung Electro-Mechanics has reduced the size by about 50% and improved the electrical loss compared with past products. In addition, unlike conventional inductors that are processed in a single unit, Samsung Electro-Mechanics is made into a substrate unit, which improves productivity and makes the product thickness thinner.
Samsung Electro-Mechanics has independently developed raw materials using nano-level ultra-fine powders, and used the photosensitive process used in semiconductor production (the production method of recording circuits with light) to successfully realize the fine spacing between the coils.
Hur Kang Heon, Vice President of Samsung Electro-Mechanics Central Research Institute, said, “As electronic products improve in performance and have more and more functions, it is necessary to reduce the size of internal parts and improve their performance and capacity. For this, differentiated technologies are required. As the only company with material technology and ultra-micro technology, Samsung Electro-Mechanics is further enhancing the competitiveness of its products through the integration of technologies.” …
Samsung Electro-Mechanics has developed and produced inductors since 1996. In terms of miniaturization, it is considered to have the highest level of technical capabilities in the industry. Samsung Electro-Mechanics plans to expand its product lineup and market share through ultra-leading technologies such as raw material development and ultra-micro technology.
It is expected that with the high performance and multi-functionalization of electronic devices, the active 5G communication and the development of the wearable device market, the demand for ultra-miniature inductors will increase rapidly, and the number of installations in electronic devices will increase by more than 20% every year in the future.

MLCCs and inductors are passive components that control voltage and current to make electronic devices work smoothly. Because each part has different characteristics, it needs to be installed in the electronic equipment at the same time. Generally, capacitors are for voltage, and inductors are for current, preventing them from changing sharply and providing stable energy for semiconductors.
