Tantalum capacitors are a little bit more expensive than
aluminum electrolytic capacitors. Capacitance can change
with temperature as well as frequency, and these types are
very stable. Therefore, tantalum capacitors are used for
circuits which demand high stability in the capacitance
values. Also, it is said to be common sense to use tantalum
capacitors for analog signal systems, because the
current-spike noise that occurs with aluminum electrolytic
capacitors does not appear. Aluminum electrolytic capacitors
are fine if you don't use them for circuits which need the
high stability characteristics of tantalum capacitors.

Answer / kamaljeet

They are used for power supply rail decoupling in parallel
with film or ceramic capacitors with low ESR and reactance
at high frequency.Equipment such as medical electronics and
space equipment that require high quality and reliability
make use of tantalum capacitors.

. For the FIFA world cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Paul picks A with the same probability as A's chances of winning. Let's assume such rumors to be true and that in a match between Ghana and Bolivia, Ghana the stronger team has a probability of 9/10 of winning the game. What is the probability that Paul will correctly pick the winner of the Ghana-Bolivia game?
