REVERSE VOLTAGE

Solid tantalum capacitors are polarized device and may be permanently damaged or destroyed, if connected with the wrong polarity.

The tantalum capacitors must not be operated and changed in reverse mode. And also the capacitors must not be used in an only AC circuit.

The tantalum capacitor dielectric has a rectifying characteristics. Therefore, when a reverse voltage is applied to it, a large current flows even at a low reverse voltage.As a result,it may spontaneously generate heat and lead to shorting.

Make sure that the polarity and voltage is correct when applying a multi-meter or similar testing instrument to the capacitors because a reverse voltage or overvoltage can be accidentally applied.

When using the capacitors in a circuit in which a reverse voltage is applied, consult your local SAMSUNG ELECTRO-MECHANICS agent. If the application of an reverse voltage is unavoidable, it must not exceed the following values.

At 20°C: 10% of the rated voltage of 1 V, whichever smaller.

At 85°C: 5% of the rated voltage or 0.5 V, whichever smaller.
