1. Introduction 1.1. Background. Solid tantalum capacitors are polarized devices designed to operate only under forward voltage bias conditions.Application of reverse voltage may produce high leakage currents with potentially destructive results.
These experimentssuggested that while solid tantalum capacitors can survive substantial reverse bias without failure, this behaviorsignificantly varies from manufacturer to manufacturer. Solid tantalum capacitors have been widely used in electronics, including military and aerospace applications, formore than 20 years.
When tantalum capacitor is used at high frequency circuit, please note that the electrical characteristics may change drastically. Leakage current value differs depending on the voltage applied. Please use higher ratings, especially when it is used in the integration circuit or time-constant circuit.
As it was shown in our experiments, a characteristic feature of reverse currents in tantalum capacitors is gradualincrease with time (for several hours) following a relatively short period of current decrease.
Reverse bias test cycles of 50V tantalum capacitors at different voltages. Different lines indicatedifferent cycles of reverse bias stress. Note that the interim measurements during tests at 3V, 5V, and 7V wereperformed at a forward voltage of 10V. The interim measurements during the 9V testing were performed at 50V.
