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.
