The global market for Aluminum Electrolytic Capacitors is projected to reach US$5.54 billion by 2022, driven by growing demand for quality capacitor solutions in automotive, telecom, and medical electronics markets.
Aluminum electrolytic capacitors (AECs) are a category of electrolytic capacitors, in which aluminum foil performs the role of anode with electrolyte functioning as cathode. AECs, designed to perform typical capacitor functions such as filtering, storing, and timing of electrical current, offer wide array of benefits in terms of functionality, performance and availability that advocate their use in numerous applications. While technical and performance features such as high capacitance, relatively higher energy density, no peak current limitation, and support for fully customized designs, propel the sales of AECs across various applications; wider availability of devices from a huge number of capacitor suppliers and at low prices, make AECs one of the most sought after capacitors within the broader capacitors market. Leveraging the unique characteristics, AECs offer ideal capacitor solutions and are used in several general-purpose and special-purpose applications. Some of the general-purpose applications of AECs include standard power supplies, SMPS, DC-DC converters, frequency converters, and inverters among others. Select special-purpose applications are frequency coupling, strobe applications, etc.
The global market for AECs is currently witnessing mixed demand patterns across key end-use segments. Demand is declining in Consumer Electronics and Computers & Peripherals segments, on the back of stagnation in sales of some conventional AV systems such as DVD systems and stereo systems etc., and also due to emergence of smartphones and tablet PCs, which use MLCCs in place of AECs, as entertainment devices and computing solutions for modern population. Since the two end-use segments collectively account for about 45% of total value shipments, the declining demand is having a major bearing on overall market prospects. On the other hand, AECs market is witnessing stable demand in industrial applications, driven by growing deployments of inverter-driven systems, electronics-based automation equipment, IoT and M2M communication systems in industrial environments. At the same time, the market is also experiencing significant opportunities in the telecommunications, automotive and medical/defense/mining equipment markets, aided by growing use of electronics in the respective segments.
China represents the largest market worldwide. Well-established industrial sector and thriving electronics manufacturing ecosystem along with steadily expanding telecommunications and automotive industries continue to favor growth AECs market in China.
