Small Cell Capacitors

Maxwell Technologies Nesscap Small Cell Ultracapacitors are high-performance capacitors with low equivalent series resistance (ESR). These capacitors offer superior shock and vibration resistance as well as long lifetimes with up to 500,000 duty cycles. The devices are compliant with UL, RoHS, and REACH requirements. Typical applications for Maxwell Technologies Nesscap Small Cell Ultracapacitors include actuators, emergency lighting, telematics, automotive, security equipment, backup systems, smoke detectors, advanced metering, and more.
