The PTV-6R0V505-R from Eaton is a Cylindrical Supercapacitor that is ideal for RF radio pulse power, automotive pulse power, valves and actuator power, and industrial backup/ride-through applications. It has a capacitance of 5 F and a capacitance tolerance from -10% to +30%. This supercapacitor has a voltage rating of 6 V and an equivalent series resistance (ESR) of less than 72 milli-ohms. It utilizes electric double layer capacitor (EDLC) construction along with proprietary materials and processes to offer a wide variety of capacitor solutions tailored for backup and hybrid power systems. This supercapacitor can be used either as sole energy storage or in combination with batteries to optimize cost, lifetime, and run time. It is useful for applications requiring high power density with environmentally-friendly materials. This RoHS-compliant supercapacitor is available in a through-hole package that measures 21.3 x 32.5 mm.
