High performance double-layer capacitors from NIC Components


The world is evolving quite rapidly, especially with respect to how populations in developed nations create and use power. Green energy sources are being introduced to the grid quickly, and the electrification of everyday products is a strong trend. A key technology supporting this is the supercapacitor, because it helps fill the gap between traditional capacitors and rechargeable batteries. This article explores new double-layer supercapacitor technology from NIC Components.

NIC Components (NIC), a market leader in performance passives, offers a diverse range of high-quality double layer capacitors, also known as supercapacitors. These capacitors utilize the latest double-layer technologies to achieve remarkable energy and power densities, making them ideal for a wide range of energy and power applications.

With over 15 unique supercapacitor series, NIC provides options across single-cell, radial can type, and series connected configurations. Each category offers specialized features such as operating temperature range, voltage, and equivalent series resistance (ESR), providing endless options for power-backup applications including energy storage, IoT data transmissions, memory backup, and real-time-clock (RTC) applications.

Within the low current, memory backup family, NIC's legacy and focus series include the NEXC(W) and NEXT. The NEXC series, available in 3.6VDC and 5.5VDC with a capacitance range from 0.047F to 1.0F, features SMT V-Chip constructions that aid backup circuits in applications like measurement and control systems. The NEXCW option extends the operating temperature range to -40 ~ 85C, catering to transportation and smart metering applications. The NEXT series excels in boost discharge applications, offering the lowest ESR performance for HDDs, motors, printers, and relays.

NIC has recently introduced the NDLC and NDLW single-cell supercapacitors within the low current memory backup lineup. These capacitors, available in button radial, horizontal axial, and vertical axial constructions, provide competitive performance options, expanding the range of applications.

For energy backup, NIC offers four radial can construction supercapacitor series. These capacitors, rated at 2.7V and 3.0V, have a large capacitance range from 0.5F to 100F and boast various features to cater to different requirements. The NDRL series offers a standard operating temperature range of -25 ~ 70C and 2.7VDC voltage operation. The NDRZ series provides lower ESR and high peak current capabilities, also with a standard operating temperature range of -25 ~ 70C and 2.7VDC voltage operation. The NDRH series supports 3.0VDC voltage operation, while the NDRW series extends the operating temperature support to -40 ~ 85C. These capacitors are well-suited for applications in lighting, industrial equipment, and power tools.

NIC's energy backup supercapacitors are available in a single package with two capacitors connected in series, creating a power backup supercapacitor. This series connection allows for 5.5VDC and 6.0VDC operations while maintaining exceptional energy and power densities. The NDCS utilizes the NDRL standard range series, while the NDCH achieves 6.0VDC voltage operation using the NDRH series. The NDCW series, built from the NDRW series, provides extended operating temperature support of -40 ~ 85C. These power backup components, with their high energy and power densities, are well-suited for technical applications such as DDR power backup, power assist circuits, and energy harvesting.
