Low leakage current supercapacitors tout small footprint
Cellergy has announced its CLC Series, offering low leakage current (LC) for its small footprint products (12 mm x12.5 mm), with heights ranging from 2.4 mm to 3.6 mm. The maximum LC for single cell configurations is 1.5 µA and for double cell configurations is 3 µA. The supercapacitors are suited for pulse applications and are frequently used in conjunction with batteries to assist in delivering energy to the load. The new supercapacitors meet the needs of such low LC applications as RFID tags and wireless alarm systems, medical systems, low power transmitters, and remote controls. Other applications include energy harvesting (including WSN wireless sensor networks), audio systems, memory back-up, and as replacements for tantalum capacitors. The CLC supercapacitors are offered with 3.5 mΏ, 4.2 mΏ, and 5.5 nominal voltages, ESRs from 300 mΏ to 720 mΏ, and capacitances from 10 mF to 25 mF. The supercapacitors are suitable for pulse applications which require high capacitance and low voltage drop. Supercapacitors bridge the gap between the power delivery limitations of batteries and the energy delivery capabilities of conventional capacitors, allowing for unlimited high pulse currents, and enabling reduction of the voltage drop in battery-operated applications.
