Sorted by: 2. 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.

A 10uF ceramic or film capacitor would be expensive. Typically, anything above 1uF is usually electrolytic or tantalum. (Tantalum caps are a type of electrolytic.) A power supply filter capacitor would typically be 1000uF or more. Switching power supplies (that operate at higher frequencies) might use something like 100uF.

Where, I PEAK is the peak surge current (A), V R is the rated voltage (V), 0.45 is the external test circuit resistance (Ohm), ESR is the equivalent series resistance of the tantalum capacitor (Ohm). I PEAK is the maximum DC current that the tantalum capacitor can safely withstand during its normal operation. If a tantalum capacitor with …
In the tantalum electrolytic capacitor, the distance between the plates is very small since it is only the thickness of the tantalum pentoxide film. As the dielectric constant of the …
A tantalum capacitor is a passive electronic component that stores energy in an electric field. The name comes from the element tantalum, which is used to make the ceramic or tantalum oxide plates inside the capacitor. The internal plates are separated by a thin layer of electrolyte, which is usually a solid or gel.
Each output capacitor (red arrows in Figure 4) was changed for the desired mix of electrolytic and ceramic capacitors. C OUT was changed to two 100-µF electrolytic capacitors from the tool's database and C OUTX to a ceramic capacitor. The database has several suitable ceramic capac-itors. However, the tool did not have the 22-µF ceramic
More than half of tantalum's use is for electrolytic capacitors and vacuum furnace parts. The element is also used to make chemical process equipment, nuclear reactors, aircraft and missile parts.
An electrolytic capacitor contains two conductive plates, an insulating layer, and an "electrolyte" liquid such as boric acid. Because of the chemical construction, one plate becomes the anode, or positive, and one plate becomes the cathode, or negative. The basic electrolytic capacitor is aluminum oxide and it looks like a cylinder with two legs.
An electrolytic capacitor is a polarized capacitor that utilizes an oxide layer on an anode or positive metal plate to provide capacitance. These capacitors are commonly used in flash memory manufacturing to store and release electric charges, providing emergency power supplies in case of sudden power failures.
According to capacitor theory, capacitance is determined by the following formula: where is the dielectric constant for free space (8.855 x 10 −12 Farads / m), ε is the dielectric constant for tantalum pentoxide (about 27), A is the surface area in m 2, and d is the dielectric thickness in m.In these parameters, is a constant and does not vary with …
If water is fully removed the tantalum capacitor survived in vacuum for much longer periods of time, and at higher temperatures than were expected. 2. Capacitors would recover to lower currents when temperatures were lowered. 3. When dry, the capacitors could be used at temperatures at least as high as 55C without affecting the life of the ...
Tantalum capacitors are electrolytic capacitors, which means the capacitor is formed by an oxide layer formed on the anode and is thus polarized. A tantalum capacitor includes a tantalum powder anode, a Ta2O5 oxide layer dielectric, and a cathode that can be MnO2 or a solid polymer.

They can become unstable when a low ESR capacitor is placed across their output (such as a tantalum capacitor) and may oscillate, especially at low temperatures. If a circuit must use tantalum capacitors instead of aluminum electrolytic capacitors, resistors in series are added to emulate aluminum electrolytic capacitors.
Tantalum capacitors increases distortion because the capacitance alters with (a) applied DC bias voltage, (b) applied AC voltage, and (c) frequency; the effects are consequently non-linear (higher on one side than the other) and thus harmonic distortion. The THD of a tantalum capacitor exceeds that of ceramics, which are awful.
Using a tantalum as a coupling capacitor, that I have never tried - no real reason to when a cheap aluminum electrolytic does the job just fine @ audio frequencies. Keep the f3 well below 10hz - if you don't you'll wind up introducing distortion into the low frequencies. 10uF-100uF is plenty.
