Demanding humidity resistance specification
A range of 225 EDLC-R ENYCAP ruggedised capacitors manufactured by Vishay/BC Components are available at RS Components. Designed for energy storage in industrial, renewable energy and automotive environments, MAL2225 polarised electrostatic double-layer capacitors (EDLCs) combine high capacity and energy density with fast charge and discharge rates.
The capacitors are said to be the industry’s first to offer a useful life of 2000 hours at +85°C and are available to meet the most demanding moisture resistance qualification: the AEC-Q200 biased 85/85 1000-hour accelerated lifetime test.
This long useful life is double that of standard EDLCs, allowing maintenance-free operation and increasing electronic design flexibility.
At 20°C the useful lifetime is upward of 10 years.
The high humidity resistance allows for use in harsh environments in applications such as micro-UPS power sources, burst power support, energy harvesting and recovery, robotics, handheld electronics, smart meters, solar panels and emergency lighting.
MAL2225 capacitors have a rated voltage of 2.7V and offer a range of rated capacitances from 20F to 60F. Energy storage capacity per device is between 0.015 and 0.061Wh, with energy densities ranging from 2.2 to 4.1Wh/kg.
Maximum peak charge/discharge current is between 20 and 35A.
