Samsung SCLSeries manual Operating Voltage, Power Supply Circuit, 100 125

APPLICATION MANUAL

The operational attentions to the use of the tantalum capacitors are as follows:

-Electrical

-Environmental

-Conditions for mounting on equipment and circuit boards

-Mechanical vibration, shock

If the tantalum capacitors are used without satisfying any one of these conditions, the probability of short-circuiting, leakage current, ignition or other problems to occur increases. To avoid such problems, observe the following precautions when using the tantalum capacitors.

●OPERATING VOLTAGE

▶The voltage derating factor should be as great as possible. Under normal conditions, the operating voltage should be reduced to 50% or less of the rating. It is recommended that the operating voltage be 30% or less of the rating, particularly when the tantalum capacitors are used in a low- impedance circuit (see Figs. 1, 2, and 3).

▶For circuits in which a switching, charging, discharging, or other momentary current flows, it is recommended that the operating voltage be 30% or less of the rating, with a resistor connected in series to limit the current to 300 mA or less.

▶When the tantalum capacitors are to be used at an ambient temperature of higher than 85℃, the recommended operating range shown in Fig. 3 should not be exceeded.
