Safety Considerations for Acetonitrile SuperCapacitors Written By: Akihiro Kado Abstract: Advancements in SuperCapacitor design and manufacturing have made them a mainstay component in power supplies and backup systems that require high power density output. SuperCapacitors have now become commonplace components in many areas of modern electronic design. They bridge an important gap between batteries – used for high density energy storage, and electronic capacitors – for local power supply stabilization and decoupling. SuperCapacitors offer the unique ability to provide large amounts of power for short periods of time. For this reason, they have found a home in applications such as electric vehicles, uninterruptible power supplies, and data storage devices. A wide variety of SuperCapacitor structures and materials have been developed,

Technical Article: Advantages of SuperCapacitors for Power Constrained Backup

Advantages of SuperCapacitors for Power Constrained Backup Written By: Johnson Jiang Abstract: In most energy storage scenarios, the tradeoffs between power density and energy density quickly come to the foreground. This is best illustrated in the automotive industry, where power density directly translates to acceleration and driving performance, while energy density translates to the total range achievable on a tank of gas or, for an electric vehicle, on a single recharge cycle. This is true across almost every application, from wearable electronics to microgrid power networks on a college campus. This whitepaper from KYOCERA AVX will explore the advantages of SuperCapacitors, circuit level, uninterruptable power, and microgrid considerations, and the benefits that make them a more reliable option than traditional

SuperCapacitors: A Reliable Backup Power Solution Written By: Johnson Jiang Abstract: Electric double-layer capacitors (EDLCs) are electrochemical capacitors called “SuperCapacitors,” or supercaps, due to their high energy density. Compared to traditional electrolytic capacitors, SuperCapacitors store electrical energy about two to three orders of magnitude higher and achieve several hundred thousand to millions of charge-discharge cycles. This advantage comes from the special construction of SuperCapacitors.

Tantalum and SuperCapacitors Enable Maintenance Free Microcontrollers Written By: Ron Demcko | Daniel West | Ashley Stanziola Abstract: Ultra-low-power microcontroller families now exist with such low power requirements that they can be powered by energy harvesting rather than battery-operated or conventional mains. These powerful MCUs enable maintenance-free control systems in applications ranging from structure/soil/water/air monitoring applications to industrial point controllers (such as smart faucets) to wearable electronics, location tracking, and even BLE beacons.

Powering IoT Modules Using Solar Panels, SuperCapacitors, and an Automatic Buck/Boost Controller IC Written By: Ron Demcko | Ashley Stanziola | Daniel West Abstract: The use of IoT modules is exhibiting a high rate of growth because of their low cost, ease of implementation, and easily documented impact upon end-user efficiency, reliability, and cost. Manufacturers, installers, and end-users of IoT modules are seeking ways to power these devices and essentially create a set-and-forget module. Set-and-forget means a significant ongoing effort to eliminate batteries or extend the life of batteries powering IoT modules. Manufacturers of IoT modules are working to reduce their designs’ power consumption and also working with IC suppliers by requesting novel chipsets to provide quality power from harvested

Reliability of SuperCapacitors: Long-Term Reliability Test Data (Part 2) Written By: Eric DeRose | Bob Knopsnyder | Bharat Rawal Abstract: Extensive testing of electronic components is required for an understanding of their device physics, their degradation behavior and their failure mechanisms for establishing their longterm reliability. Gaining a better understanding of part characteristics results in the utilization of the right part which can be recommended to customers depending on the application’s operating conditions such as voltage, temperature and relative humidity. Samples of all products produced are evaluated and tested for up to 4,000 hours to establish reliability test data. As we strive to be an industry leader in reliability of our supercapacitors or electric double-layer capacitors, we do our due

Reliability of SuperCapacitors: Unique Performance at 85°C & Self-Balancing (Part 1) Written By: Eric DeRose | Bob Knopsnyder | Bharat Rawal Abstract: Increasing use of supercapacitors on printed circuit boards (PCBs) is requiring a further understanding of the reliability of these components. As the use of these types of devices increases, the emphasis on reliability will become critical as sub-ppm failure rates are critical for minimizing and, in fact, eliminating rework of the PCBs in these applications. A broader understanding of the reliability of these devices will assist in reaching this goal. In this first of many publications, a study of our supercapacitor modules tested at 85°C at various applied voltages, at or below the rated voltage, will demonstrate the
