Targeting developers and manufacturers of smart cards, NFC tags, and other RF energy-based products, Ligna Energy released its latest compact product, the 50-mF S-Power 2R. In addition to enabling greener products, the 2R’s ultra-thin form factor serves size, weight, and power demands of next-generation small, wearable, and portable RF devices. This is especially useful in products leveraging energy harvesting, such as solar or ambient RF energy.
Made from sustainable, non-toxic, and easily recyclable materials, the S-Power 2R uses aluminum as its metal component along with activated carbon made from recovered biomaterials, resulting in a significantly lower environmental footprint. The 20- x 20-mm 2R has a maximum thickness of 0.4 mm, suiting it for slim form factors such as smart cards or asset-tracking tags—it can even be applied to curved surfaces.
Thanks to an ESR of 2.5 Ω and a life lasting over 100,000 cycles, the 2R fits well in NFC and RFID applications powered by the energy harvested from a reader’s RF field. It has a rated voltage of 2.7 V when fully charged and thus can serve devices powered by ambient light, such as wireless sensors or remote controls.
