First, text explanation
In general, the tantalum capacitor polarity, there is a horizontal line that end is anode of tantalum capacitors, the other side is the negative of tantalum capacitor; lead tantalum capacitor long legs are positive pole, short legs are negative pole, the patch of tantalum capacitors positive and negative cannot reverse, reverse the capacitor does not work.
If the polarity of the tantalum capacitor is reversed, the result of the lighter is burning of the tantalum capacitor; the serious consequence is the explosion of the tantalum capacitor. Tantalum capacitor explosion will affect other components on the PCB, so we must be very cautious.
Second, picture interpretation
The following picture shows the positive pole of the tantalum capacitor, of course, there is no indication the anode of the tantalum capacitor.
Third, corresponding of the schematic diagram and PCB package.
