Ripple current ratings for all devices can be calculated. For 25°C ripple current ratings, take the square root of the
part’s free air maximum power dissipation in watts (from the table below) divided by the maximum ESR rating of the
component listed in the catalog in ohms (where applicable, convert milliohm values to ohms). Apply the temperature
correction factor for temperature above 25°C.
DC Leakage current is dependent on the voltage applied, elapsed time of voltage applied and temperature.
Leakage current is measured after 3-5 minutes application of the rated voltage at +20°C. Leakage current increases
with higher temperatures and can be mitigated by increasing the voltage rating of the part. Leakage current drops
rapidly below the parts initial value when reduced voltages are applied. Voltage derating of the component has the
effect of decreasing leakage as shown in the graph below. This will also give a significant increase in the reliability
of the part for any application.
Self Inductance Value (ESL) for surface mount devices
The self inductance value can be important for resonance frequency evaluation.
This table shows typical ESL values per case size.
Recommended storage conditions
Solid tantalum capacitors are known to have an infinite shelf life at werehouse storage conditions maintained at a
temperature of +15°C to +35°C and a relative humidity at 25% to 75%.
Storage conditions at temperatures of -10°C to +50°C are acceptable, but in excess of two years of exposure to these
conditions with high humidity, leakage current may be affected.
