The tantalum capacitor polarity and markings are discussed below. Tantalum capacitors are innately polarized capacitors with positive and negative lead and are appropriate with DC supplies. The polarity and markings on the capacitors make it easy to identify the anode and cathode. Two bands and a positive sign helps in identifying the …
Radial, surface mount cans will have a colored portion on the top indicating the negative pad. Axial cans will have a line on one side with arrows pointing to the negative lead, or an indented band that designates the positive lead. Surface mount tantalum chips will have a line and/or a notch on the positive end.

Aluminum electrolytic capacitors, tantalum electrolytic capacitors, conductive polymer (electrolytic) capacitors, and electric double layer capacitors fall into this category. ... PPS and PEN, which feature high heat resistance, are used in surface mount type film capacitors. In terms of electric characteristics, PEN is close to PET, …
A capacitor is a passive electronic device that stores electric charge. Tantalum capacitors have an anode electrode (+) made of tantalum metal, electrolyte that acts as the cathode, and a thin insulating layer of tantalum oxide that acts as the dielectric. Tantalum capacitors have high capacitance-voltage (CV) product per unit volume at low ...
In general, MLCCs have lower ESR than either solid tantalum or tantalum polymer capacitors of the same voltage rating and capacitance values. For a typical 47 µF, 6.3V 1206 capacitor, the maximum 100 kHz ESR levels would be something like this: Solid tantalum ~ 0.9Ω. Tantalum polymer ~ 0.1 Ω.

Figure 6. Effect of accelerated humidity testing (PCT) at 121 oC/ RH on frequency characteristics of capacitance (a, c) and ESR (b, d) for the 10 mF (a, b) and 22 mF (c, d) capacitors. Note a significant reduction in the capacitance roll-off effect for both parts and an increase in ESR in the MHz range for the 22 mF capacitors.
10. Application Temperature (°C) As an example, if a tantalum capacitor is used without any derating, failure rates of 0.1 % to 1 % will occur. Tantalum capacitor manufacturers generally recommend that a minimum of 60 % voltage derating should be applied (if not specified differently in a product datasheet).
