Supercapacitors excel in applications requiring pulse power output

The SCM series of supercapacitors from AVX combines high capacitance with very low equivalent series resistance (ESR) to give excellent performance in applications requiring a pulse power output. 

These cylindrical electrochemical double-layer capacitor (EDLC) devices can perform more than 1 million charge/discharge cycles and offer a 4,000 hour lifetime rating, so they are also suitable for long-life applications in which a standard battery would wear out prematurely. 

Used by themselves or in conjunction with primary or secondary batteries, the SCM series supercapacitors can perform various functions: 

• Back-up power supply: providing energy to safely shut down an application on the failure of the main power supply
• Pulse power handling: assisting the primary power supply when the load requires a high current peak 
• Energy harvesting: optimizing energy usage through power regeneration or capturing power from the environment

The SCM series consists of a broad range of products, including a cell with a 6.3 mm diameter, the industry’s smallest EDLC. Voltage options are 5.0 V, 5.4 V, 5.5 V, 6.0 V, 7.5 V, 8.1 V, 9.0 V, 16 V and 48 V. The products are available with capacitance values up to 500 F.
