Table 2 - Maximum allowable ESR for tantalum electrolytics per EIA standards.
Compare the measured D/A to the amount listed in
Table 3 for the capacitor type you are testing to
determine if the capacitor is good or bad.
NOTE: Depending on the capacitor's value, type and
actual D/A, the LC103 may, in a few cases, take up to 10
seconds to display a reading.

Measuring Capacitor Leakage
Capacitor leakage occurs when some of the voltage from
one plate flows (leaks) through the dielectric to the other
plate. The amount of leakage current through the
dielectric depends on the voltage applied across the
plates. For this reason, always check a capacitor for
leakage at (or as close as possible to) its rated voltage.
Voltages up to 1000 volts may be applied with the
LC103.
Although the EIA specifies the amount of leakage in uA,
at times it is useful to know the amount of capacitor
leakage in terms of resistance. For example, it is often
easier to visualize what effect a 1 Megohm resistor will
have on a high impedance circuit than it is to translate
the effect of a capacitor having 1 microamp of leakage.
Yet, as far as the circuit is concerned, the DC loading is
the same. The LC103 uses a regulated DC power supply
to provide voltages for checking capacitor leakage.
Because a DC voltage is used, the leakage currents can
easily be converted to a resistance. The ReZolver
simultaneously displays the leakage in both uA and
Ohms.
To check capacitors for leakage, enter the working
voltage of the capacitor and press the CAPACITOR
LEAKAGE button. Compare the measured leakage
current to the maximum allowable amounts in the
leakage charts. The capacitor is good if the measured
leakage is below the amount shown in the chart. A fully
automatic GOOD/BAD test may also be used to check
capacitors for leakage.
