Are tantalum capacitors leaky?

The leakage current of a solid tantalum capacitor is normally expressed as a single value measured at room temperature, at rated voltage, and after 3 or 5 minutes. This value is classed as high or low in comparison with a selection limit of typically 10nA/µFV (e.g., 3.3µA for a 33µF 10V capacitor).

What is capacitor derating?

Capacitors are derated by limiting applied voltage and operating temperature. Additional derating is necessary for ripple current for capacitor styles that substantially degrade due to the temperature effects of high ripple current.

How long do tantalum capacitors last?

Capacitance stability Whilst MLCCs are susceptible to aging, polymer tantalums achieve long-term stability over an operational lifetime of 20 years.

Do tantalum capacitors explode?

Full Member level 2. They do explode specially when there is voltage surge or voltage applied to them is greater than their rated voltage,tantalums are very prone to voltage surge and can not survive in such condition as a results may explode immediately.

How do you find the derating factor of a capacitor?

Category Concepts and Derating Derating is expressed usually by percentage of rated voltage that shall be subtracted. For example 20% derating means that the capacitor shall be used at 80% of rated voltage at the specific applications (10V capacitor to be used on 8V maximum).

Can I use electrolytic capacitor instead of tantalum?

Yes, you can change it for Tantalum capacitors. The zobel capacitor can be ceramic or nylon. C7 probably you can’t find any of this value 0.1uF but you can change it to 1.0uF this will give some aditional bass to your amplifier; however if you use any ceramic capacitor won’t have any problem.

Why use tantalum capacitors over ceramic?

When looking at capacitance changes with applied voltage, tantalum capacitors show consistent stability whereas ceramic capacitors do not. In response to higher applied voltages, the permittivity of the dielectric shrinks within the ceramic capacitor and causes changes in capacitance.
