I'm examining a data sheet for a supercap for a memory hold-up application.
Normally Nichicon has great products and this supercap may be another except they've got some cockamamie brief statement of what the ALL IMPORTANT leakage current is. No where do they define it clearly - to me anyway.
In the following data sheet they state:
Leakage Current | 0.5C(mA) [C:Rated Capacitance(F)]

General Nichicon SuperCap data sheet.

Could they really mean that a 1Farad offering is going to have a 500uA leakage current??!! That's 50 times more leakage than the next company's offerings.
