The DDXG2R5LGN301EB65S from Nippon Chemi Con is an Electric Double-layer Capacitor ideal for electricity storage, battery assistance, short-term backups, and efficient engine cranking in automobile applications. It has a capacitance of 300 F and a capacitance tolerance of 0-20% This supercapacitor has a voltage rating of 2.5 V and an equivalent series resistance (ESR) of less than 1.6 milli-ohms. It will guarantee a useful lifetime of 3000 hours at +70 °C and further improves the power density compared to traditional supercapacitors, thereby enhancing low-temperature performance and supporting high-temperature environments. This RoHS 2-compliant supercapacitor is available in a screw-mount package that measures 40 x 65 mm.
