8. Per United Nations material classification UN3499, all
Maxwell ultracapacitors have less than 10 Wh capacity
to meet the requirements of Special Provisions
361. Both individual ultracapacitors and modules
composed of those ultracapacitors shipped by
Maxwell can be transported without being treated
as dangerous goods (hazardous materials) under
transportation regulations.
9. Duration = 60 seconds. Not intended as an operating
parameter.
