Würth Elektronik WCAP-SISC supercapacitors

Würth Elektronik has introduced a class of EDLC (electric double-layer capacitor) supercapacitors with snap-in terminals. The WCAP-SISC series — available with capacitance values of 100 and 350 F — is suitable for applications with high power and high energy requirements such as UPS or energy storage solutions. They can be used in smart metering devices, network components or energy harvesting applications to name but a few. The product attains a rated current of up to 75 A.

With higher energy density compared with conventional capacitors, double-layer capacitors are seen as an environmentally friendly alternative to batteries. Compared to Li-ion batteries, the supercapacitor with activated carbon technology offers numerous benefits, including fast charging, long service life of 500,000 cycles and low fire hazard. The capacitance tolerance is ‑10 /+30% and the rated voltage is 2.7 V. The product can be used at an operating temperature of -40 to +65°C.
