TAIYO YUDEN Commercializes the Electric Double-Layer Capacitor LT Series
Improved characteristics at low temperature, making the products optimal for smart meters
SAN JOSE, Calif., July 16, 2021 /PRNewswire/ -- TAIYO YUDEN CO., LTD. announced the commercialization of its cylinder-type electric double-layer capacitor LT series featuring eight products, including the LT08202R7335 (φ8.0 × 20 mm, nominal capacitance 3.3 F).
Example applications for these new capacitors include peak assistance and backup power supply in smart meters, drive recorders, and servers. The electric double-layer capacitor LT series features reduced initial AC internal resistance and more moderate changes in characteristics at low temperature when compared with the conventional LP series.
Production of the capacitors will commence at TAIYO YUDEN's subsidiary company, TANIN ELNA CO., LTD. (Chiang Mai, Thailand), in July 2021. The sample price for the LT08202R7335 is 80 yen per unit.*1
Technology Background
Smart meters, which require a large amount of energy within a short period of time for wireless data transmission, are equipped with a power storage device to supplement their power supply for peak assistance. On the other hand, servers and drive recorders require an emergency backup power supply to protect data in the event of an emergency, such as a power failure or accident. In addition, power storage devices are expected to maintain their characteristics at low temperature, as smart meters and drive recorders are used outdoors and in other low-temperature environments.
In response to this market demand, TAIYO YUDEN commercialized its cylinder-type electric double-layer capacitor LT series featuring eight products, including the LT08202R7335. Compared with the conventional LP series, the products demonstrate more moderate changes in characteristics at low temperature. We will continue to develop our power storage device products in response to market demand.
