Why do tantalum electrolytic capacitors fail?

In solid tantalum electrolytic capacitors the heat generated by the ripple current influences the reliability of the capacitors. Exceeding the limit tends to result in catastrophic failures with shorts and burning components.

What is the ripple capability of a solid tantalum electrolytic capacitor?

(4) Ripple Capability The ripple capability of solid tantalum electrolytic capacitors is defined by both Equivalent Series Resistance (ESR) and power dissipation due to ripple current. If the capacitor sees a higher than specified amount of ripple current, heat generation within the capacitor will increase eventually causing a failure.

Are aluminum and tantalum electrolytic capacitors standardized?

The tests and requirements to be met by aluminum and tantalum electrolytic capacitors for use in electronic equipment for approval as standardized types are set out in the following sectional specifications: Tantalum capacitors are the main use of the element tantalum. Tantalum ore is one of the conflict minerals.

What is the impedance of a tantalum electrolytic capacitor?

In data sheets of electrolytic capacitors, only the impedance magnitude |Z| is specified, and simply written as "Z". Regarding to the IEC/EN 60384-1 standard, the impedance values of tantalum electrolytic capacitors are measured and specified at 10 kHz or 100 kHz depending on the capacitance and voltage of the capacitor.

Who invented a tantalum electrolytic capacitor?

In 1956, H.E. Haring and R.L. Taylor from Bell Labs designed the first generation of solid tantalum electrolytic capacitors, which utilized tantalum pentoxide (Ta 2 O 5) as the dielectric layer, manganese dioxide (MnO 2) as the cathode material, and graphite silver paste as the auxiliary cathode layer .
