I am using a tantalum capacitor of 10 uF rated at 20V as a decoupling capacitor. It is placed in parallel with a 5V supply. Now when the circuit is powered, the capacitor burns out.
I replaced the tantalum capacitor assuming that the previous capacitor was defective. But when I powered the circuit the capacitor burned out again.
I replaced the tantalum capacitor with electrolytic capacitor of 10 uF rated at 63V. This time the capacitor did not burn after powering the circuit.
I do not understand why the tantalum capacitor burns up?
