Examples of Technology Application ~Product Introduction~ Strengths of Murata’s Inductor Product Line (Inductors and EMI Suppression Filters) Leveraging Winding Technology

Murata’s inductor product lineup is built on three core strengths: proprietary material technologies and long-cultivated expertise in winding processes, lamination processes, and photolithography processes. By integrating these strengths, Murata delivers products that achieve both miniaturization and high performance.
Murata combines dielectric technologies cultivated through Multilayer Ceramic Capacitors (MLCC) with in-house-developed magnetic materials with high permeability and low dielectric constant. This combination enables high performance across a wide frequency range. Depending on the application, Murata selectively uses ceramic magnetic materials, metal magnetic materials, non-magnetic ceramic materials, and other material systems. By further combining these materials with magnetic resins, insulating resins, and various other resins, Murata efficiently enhances product performance.
In winding processes, Murata has established technology for winding ultra-fine Cu (copper) wire onto cores as small as 0.6 mm in length. In addition, highly reliable molded resin encapsulation and efficient production equipment enable both mass production and high-mix manufacturing. In lamination and photolithography processes, Murata utilizes technologies for stacking ferrite sheets with thicknesses on the order of several tens of µm (micrometers), as well as photolithography and film technologies that excel at forming complex patterns. Through the optimal combination of these diverse materials and processes, Murata continues to provide the most suitable inductor product lineup for a wide range of devices.

Murata's inductor product line has steadily improved in performance and functionality alongside the evolution of electronic devices. To respond to design trends such as increased component counts and reduced mounting space driven by higher functionality and miniaturization, Murata has integrated its proprietary elemental technologies. While maintaining electrical performance, Murata has at times anticipated required sizes and supplied products to the market ahead of demand.
Notably, in the early 2000s, we developed metal alloy inductors using metallic magnetic materials. These power inductors achieved both miniaturization and high current capacity, enabling the downsizing and high performance of various electronic devices.
More recently, Murata successfully developed and prototyped a 016008-size chip inductor (0.16 mm × 0.08 mm), which reduces volume by approximately 75% compared with the previously smallest 0201-size product (0.25 mm × 0.125 mm). Murata aims to commercialize this product and continue expanding the possibilities of electronic device design through even smaller components.

Murata’s inductor product lineup is used in smartphones, home appliances, automobiles, and a wide range of everyday electronic devices, supporting both power supply circuits and communication circuits. These inductors play a critical role in ensuring stable and reliable device operation.
In recent years, Murata has focused on expanding its lineup of inductors for high-speed automotive interfaces and for power lines compatible with PoC (Power Over Coax). As PoC adoption advances in automotive cameras—where both video data and power are transmitted over a single coaxial cable—the use of inductors specifically designed for in-vehicle PoC applications is increasing.
This approach enables a reduction in the number of inductors previously required, contributing to overall system miniaturization, space savings, and reduced total DC resistance. Murata will continue to meet diverse customer needs by proposing optimal components based on specifications and by providing comprehensive noise suppression solutions. Through these efforts, Murata will continue to contribute to solving user challenges across a wide range of applications, including the automotive market.
