Table 4 - Maximum allowable leakage for aluminum electrolytics per EIA standards.
Leakage charts
The following leakage charts list the maximum amount
of allowable leakage for the most common aluminum
electrolytics and dipped solid tantalum capacitors. These
charts are also duplicated on the PULL CHART below
the LC103. Good capacitors (as far as leakage is
concerned) will measure lower than the amounts shown
in the Leakage Charts. When measuring leakage, you do
not need to wait for the readings to drop to zero or to its
lowest point. The capacitor is good for any leakage
reading which is lower than the amount shown in the
chart.
Leakage values shown in Table 4 for aluminum
electrolytic capacitors are the worst-case conditions, as
specified by the Electronic Industries Association (EIA)
standard RS-395. The values are determined by the
formulas: L = 0.05 x CV (for CV products less than
1000) or L = 6 x square root of CV (for CV products
greater than 1000. (The CV product is equal to the
capacitance value multiplied by the voltage rating).
The tantalum capacitor leakage values listed in Table 5
are for the most common type of tantalum capacitors -
dipped solid, type 3.3. These values are specified by EIA
standard RS-228B, following the formula: L = 0.35 x
square root of CV. In a few applications outside of
consumer service, tantalum capacitors other than type
3.3 may be encountered. Refer to the manufacturers
specifications for the maximum allowable leakage for
these special capacitor types.
