Multilayer ceramic capacitors, Polymer aluminum electrolytic capacitors, Silicon capacitors, High temperature film capacitors for automotive, etc.
Net sales (Billion yen)
In fiscal 2018, sales of multilayer ceramic capacitors for car electronics, the main product in this category, were strong
as vehicle electrification progressed and demand increased in a broad range of applications, including applications in smartphones in Greater China, computers and peripherals. As a result, overall net sales were 574.2 billion yen (up 27.7% year-on-year).
Initiatives in the capacitor business
In fiscal 2018, the use of electronics increased in areas such as automobiles, and demand for capacitors rapidly increased. In response to robust customer demand, Murata has endeavored to increase production capacity, while also revising our product portfolio and increasing the amount we supply. In addition, we made requests to customers to revise the sales prices of chip multilayer ceramic capacitors (MLCCs), and allocated the proceeds to investment
funds for strengthening production capacity. There is significant uncertainty regarding the direction of the global economy in fiscal 2019, which will also affect our capacitor business, but over the medium-term, we can expect new demand for applications in communications infrastructure, along with the spread of 5G, in addition to increased demand for compact large-capacity products for use in communications devices and highly reliable products for use in automobiles. We will allocate management resources to products that address this demand and develop new products, while also implementing initiatives to enhance productivity by promoting the use of smart factories.
In addition, we will enhance our range of capacitors to address the diverse needs of our customers, add non-ceramic products such as film capacitors, silicon capacitors to our portfolio, and offer new proposals with high reliability suitable for usage environments in the automotive and healthcare/medical markets.
Chip multilayer ceramic capacitors for consumer
The chip multilayer ceramic capacitor (MLCC) is an electronic component with external electrodes electrically and mechanically bonded to a substrate,
attached to repeatedly stacked internal electrodes and ceramic dielectrics such as titanium oxide and barium titanate. It is a highly reliable nonpolar capacitor with high withstanding voltage and insulation resistance, superior frequency and heat-resisting characteristics, and long service life.
MLCCs are employed in mobile devices and home appliances as well as IT devices and network infrastructure equipment as they can temporarily store
and discharge electricity, absorb noise in signals, extract signals with certain frequencies, and block direct current and pass alternating current only. MLCCs are also used for applications for which high reliability is required, including automotive, medical, and aerospace equipment. In particular, 600 to 1,000 MLCCs are used in one high-end smartphone. Even low-end or midrange models use 300 to 600 MLCCs per unit.
Regarding consumer MLCCs, to meet market demands particularly for those smaller in size, various products have been developed and have become highly competitive capacitors. Recently, the main product size has shifted from 1005M (1.0X0.5 mm) to 0603M (0.6X0.3 mm) and for wearable devices and small modules, consideration for adoption of 0201M(0.25X0.125 mm), the smallest size commercialized in 2014, has been increasing. Since market needs are expected to grow further for smaller components and high-density mounting, Murata will continue to improve its ceramic material pulverization and multilayer technology and propose new product design and easier to use solutions.
