Per United Nations material classification UN3499, all Maxwell ultracapacitors for Capacitance, ESR, Leakage Current and Self-Discharge Characterizations of Ultracapacitors available at www.maxwell.com. have less than 10 Wh capacity to meet the requirements of Special Provisions 361. Both individual ultracapacitors and modules composed of those 4. Maximum Leakage Current ultracapacitors shipped by Maxwell can be transported without being treated as Current measured after 72 hrs at rated voltage and 25C. Initial leakage current dangerous goods (hazardous materials) under transportation regulations. can be higher. If applicable, module leakage current is the sum of cell and balancing circuit 10. BOL: Beginning of Life, rated initial product performance leakage currents. EOL: End of Life criteria. Capacitance: 80% of min. BOL rating 5. Maximum Peak Current ESR : 2x max.
