    What Are Tantalum Capacitors?CharacteristicsConstruction and Properties of Tantalum CapacitorsApplications For Tantalum CapacitorsTantalum capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal which acts as an anode, covered by a layer of oxide which acts as the dielectric, surrounded by a conductive cathode. The use of tantalum allows for a very thin dielectric layer. This results in a higher capacitance value per volume, superior frequency characteristics compared to many other types of capacitors and excellent stability over t在capacitorguide上查看更多信息

    An electrolytic capacitor (occasionally abbreviated e-cap) is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Due to their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage(CV) product per unit vol

    2015-10-22  I replaced a 1000uF 16V electrolytic on my PC power supply once with a 10uF 25V wet slug tantalum unit, as I needed a capacitor and this was the only one to hand. Worked well for years afterwards, even though the current in the cap was large. the ripple was lower than what the original capacitor had. This was in a LC output filter on the 5V rail, where the original popped it's top.

    "When used properly" tantalum capacitors are highly reliable. They have the advantage of high capacitance per volume and good decoupling characteristics due to relatively low internal resistance and low inductance compared to traditional alternatives such as aluminum wet electrolytic capacitors. The 'catch' is in the qualifier "when used properly".
