6 FAQs about [What technology does tantalum capacitor belong to ]
What is a tantalum capacitor made of?
A tantalum capacitor consists of a tantalum metal anode, a dielectric oxide layer, and a cathode (usually made from a liquid or solid electrolyte). The tantalum anode forms the positive side, while the cathode forms the negative side. The oxide layer acts as the dielectric, enabling the capacitor to store electrical charge.
Are tantalum electrolytic capacitors polarized?
Tantalum electrolytic capacitors are polarized. Polarized capacitors have an asymmetrical construction in which the anode terminal must always be more positive than the cathode terminal. In contrast, aluminum electrolytic capacitors do not offer the same capacitance per unit of volume advantage provided by tantalum capacitors.
What are the advantages of solid leaded tantalum capacitors?
They have self-healing properties, allowing thinner dielectric oxide layer, and high capacitance per unit volume. Solid leaded tantalum capacitors: They have higher capacitance density than wet aluminium electrolytic capacitors or solid tantalum type. Higher electron conductivity makes them sensitive to voltage spikes or surge currents.
What temperature can a tantalum electrolytic capacitor be used in?
Tantalum capacitors (like aluminum electrolytic capacitors) thrive in the military temperature range of -55° C to 125° C. This opens commercial applications (0 to 70° C), industrial uses (-40° C to 85° C) and automotive products (-40° C to 105° C). Construction of a surface mount tantalum electrolytic capacitor. (Image: Rohm Semiconductor.)
What are Talum electrolytic capacitors?
Tantalum electrolytic capacitors are often used as an upgrade technology to replace aluminum electrolytic capacitors. It’s important to contrast the two technologies. Tantalum capacitors have thin dielectric layers that result in higher capacitance per unit of volume when compared to aluminum electrolytic capacitors.
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.
