There is a growing expectation of consumers to be connected to everything they use on a daily basis. This is come to be known as the IoT. Items that were not previously connected to the internet, such as vehicles, home appliances, electric power meters, industrial machinery and infrastructure, factory manufacturing equipment and even wearable are being connected using telecommunication and networking systems. This is leveraging interoperability with other devices to create new products and services using big data.
NICHICON announces a new capacitor that will contribute to these IoT systems as the market for home and industrial monitoring expands with the use of surveillance cameras and home appliances.
■Development of Electric Double Layer Capacitors for the IoT Market
Amid these market developments, NICHICON has developed the ultrafine electric double layer capacitor. Until now, the φ6.3×9L(mm) size had a maximum 1F storage capacity. We have successfully developed an ultrafine electric double layer capacitor with the same storage capacity (1F) in a φ4×30L(mm) size through the development of high capacity electrodes, as well as the development of production technologies with improved precision. This is ideal for thin products such as smart eyewear and stylus pens. They also have the added capability of being able to be charged even with a very low current, which is expected to encourage the spread of this technology to applications in areas such as energy harvesting.

■Development of Conductive Polymer Hybrid Aluminum Electrolytic
On the other hand, conductive polymer aluminum solid electrolytic capacitors use conductive polymers for cathode materials, which enable support for low resistance and high ripple current, as conductive polymer is electron conductive. Also, there is minimal change in characteristics due to temperature and no dry up, enabling long life and usage in a variety of temperature regions. However, compared to electrolytes, conductive polymers have low electrolyte dielectric oxide film reparability, thus it was difficult to use in applications requiring low leakage current.
NICHICON developed the GYA series of conductive polymer hybrid aluminum electrolytic capacitors (guaranteed for 4,000 hours at 125°C) to leverage both these advantages while compensating for the drawbacks of the above mentioned capacitors. This capacitor uses a hybrid electrolyte solution combining conductive polymer and electrolytes realizing long life and low leakage current characteristics due to the low ESR characteristics of conductive polymer and electrolytes and the use of a newly developed electrolytic solution compatible with conductive polymer. The use of conductive polymer also enables a longer life, enabling use in a variety of applications, including vehicles, power sources, telecommunications equipment, home appliances and light fixtures.
Going forward, we think the market will continue to grow amid expanding conductive polymer hybrid aluminum electrolytic capacitor usage applications. NICHICON plans to expand its lineup of high-performance conductive polymer hybrid aluminum electrolytic capacitors to respond to demands for enhanced storage capacity, higher heat tolerance, lower resistance, longer life and higher voltagewithstanding.
