6 FAQs about [How do tantalum capacitors store energy ]
What is a wet tantalum capacitor?
Wet tantalum capacitors are basic to all kinds of electrical equipment from satellites, aerospace, airborne, military ground support, oil exploration, and power supplies. Their function is to store an electrical charge for later use. Capacitors consist of two conducting surfaces and an insulating material, or dielectric that separates them.
Why are tantalum capacitors important?
First, tantalum capacitors can achieve even higher CV due to its porous structure. Second, tantalum capacitors can achieve even lower ESR because of their internal structure with parallel layers and multiple anodes. Finally, tantalum capacitors are more resistant to vibration, which is especially important for automotive applications.
Do tantalum capacitors have a high volumetric capacitance?
The dielectric thickness of electrolytic capacitors is very thin, in the range of nanometersper volt. Despite this, the dielectric strengths of these oxide layers are quite high. Thus, tantalum capacitors can achieve a high volumetric capacitance compared to other capacitor types.
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.
