Chip multilayer ceramic capacitors

Operating results

For fiscal 2017, sales of multilayer ceramic capacitors (MLCCs) for communications equipment, the main product in this category, grew significantly as demand increased in a broad range of applications. New products for new smartphone models achieved much higher sales, as did MLCCs for car electronics as a result of progress in vehicle electrification. As a result, overall net sales increased to 449.8 billion yen (up 21.7% year-on-year).

Initiatives in the capacitor business

Murata is reviewing fair prices of MLCCs in addition to its product portfolio to respond to rapidly growing demand for capacitors.
Also, Murata has been developing new products ahead of competitors and expanding a global production system while maintaining high quality.
To expand the boundaries of the capacitor business, we will add film capacitors, silicon capacitors, and other non-ceramic products to our portfolio and offer new proposals with high reliability suitable to use environments in the automobile 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.
Demands for MLCCs are rapidly expanding in every market. Murata will expand its business, centering on small products with large capacities for which production is difficult for competitors due to material and technical issues.

Chip multilayer ceramic capacitor for automotive

For automotive MLCCs, stricter regulations have been set out than those of consumer MLCCs in the areas of product material selection, design standards, product performance, and process management to achieve higher reliability and longer product life, even though materials and processes are generally the same as those in consumer MLCCs.
MLCCs have been increasingly adopted for safety applications such as airbags and ABS in addition to hybrid and electric vehicles that have become increasingly widespread, and production of these packages is rapidly increasing. Moreover, components employed by many customers are becoming smaller and the main size is shifting to 1005M (1.0X0.5 mm) from 1608M (1.6X0.8 mm). Also, these satisfy requirements of temperature cycling tests and high temperature and high humidity load tests at 150°C, a step up from the previous guarantee of 125°C.  urthermore, more products meet requirements specific to in-vehicle applications regarding static electricity and surge tests (ISO7637-2). Recently, products which can be used in higher temperature environments are in demand.
To respond to tough market demands as stated above, Murata has developed more reliable materials, ensured product design margins, and established strict inspection standards for the production process to realize highly reliable products suited to use environments. In 2017, Murata succeeded in commercialization of products resistant to 200°C despite the use of lead type resin-coated MLCCs, and customer companies are considering adoption. Furthermore, various types of MLCCs according to the use environments have been commercialized, such as water-repellent products and MLCCs with metal terminals jointed.
Also in automotive MLCCs, Murata will continue to create new value for society by developing ceramic materials and improving process and inspection technologies toward creating smaller, more highly reliable and higher performance components.
Moreover, there is a strong desire in the automotive market for the stable supply of Murata’s highly reliable components, and to respond to such expectations asthe market leader, we are making maximum equipment investment at domestic and overseas plants. Murata delivers products with safety and security by identifying customers’ product and supply needs as a continuously trusted company.
