6 FAQs about [Capacitors that can replace tantalum capacitors for energy storage]

What is the difference between MLCC and tantalum polymer capacitors?

Regardless of the applied voltage, the capacitance value remains essentially unchanged. For both solid tantalum and tantalum polymer capacitors, the capacitance value increases with temperature. In summary, tantalum and tantalum polymer capacitors offer higher and more stable capacitance values than MLCCs, especially at high temperatures.

What are tantalum electrolytic capacitors?

After aluminum electrolytic capacitors gained widespread use, issues such as limited lifespan and inadequate high-temperature resistance became apparent, prompting the development of tantalum electrolytic capacitors. These capacitors, similar to other electrolytic types, consist of an anode, electrolyte, and cathode.

What is a Tantalum Polymer (Tapoly) capacitor?

Tantalum Polymer (Tapoly) capacitors are high CV devices, similar to tantalum capacitors, but offer extreme stability across temperature and voltage. Electrochemical Double Layer Capacitors (EDLC), also known as supercapacitors, have an impressive bulk capacitance value, easily achieving 3000F in a single element discrete capacitor.

Which is better MLCC or tantalum polymer electrolytic device?

So for applications that require high capacitance values, such as power filtering and bulk energy storage, the tantalum and tantalum polymer electrolytic devices will offer better capacitance retention than MLCCs with the same capacitor rating.

Which capacitors are suitable for energy storage applications?

Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.

How much voltage should a tantalum capacitor be rated?

Solid tantalum capacitors with manganese dioxide solid electrolyte (MnO2) — Industry standards call for a 50 % voltage derating Tantalum capacitors with polymer electrolyte — The suggested voltage derating should be 10 % (i.e. apply no more than 9 V on a 10 V rated capacitor) for capacitors with a voltage rating of 10 V or less.
