All tantalum capacitors have the following advantages over normal aluminum electrolytic capacitors:
(1)
Since the dielectric constant of the tantalum oxide film is 17 higher
than the dielectric constant of the aluminum oxide film, the tantalum
capacitor can achieve small volume and large capacity.
(2)
Under extreme conditions such as low temperature or high temperature,
the working performance of tantalum capacitors is much higher than
aluminum electrolytic capacitors.
(3) small leakage current, tantalum capacitor filtering ability is its famous one.
(4)
When the operating frequency is high, the capacity of the tantalum
capacitor drops slower than that of the aluminum electrolytic capacitor,
and its usable capacity is larger than that of the aluminum capacitor.
(5)
long life, high reliability, due to the durability of tantalum,
tantalum capacitor failure probability is much smaller than the aluminum
capacitor, would like to encounter a failure of tantalum polymer
capacitors to wait more than 110 years, which is why the US military to
use large amounts of tantalum capacitors .
