Tantalum - Polymer Capacitors

What is Tantalum - Polymer Capacitors?

Polymer capacitors, also called polymer electrolytic capacitors, are a sort of electrolytic capacitor. A capacitor is a two-terminal electrical device that is capable of storing current, somehow like a battery. Polymer capacitors contain conductive polymer as their electrolyte substance, which is embedded in a layered aluminum design. These capacitors integrate distinguishing features from the polymer material in terms of potential conductivity, widened temperature range, and mitigate the risk of drying out at all; capacitors must offer potential capacitance capability and an extremely low equivalent series resistance with high ripple voltage capability and provide extended operating life. A conductive polymer is used in place of a liquid electrolyte as one of the properties of polymer capacitors, which come in a variety of packaging configurations ranging from 2.2 to 470 microfarads. Capacitors may also be referred to as wet, indicating they have a liquid or solid electrolyte, depending on the kind of electrolyte. Solid electrolytes, which often relate to tantalum or polymer-based capacitors, may be hybridized with aluminum.

Why do tantalum capacitors explode?

In particular, when there is a voltage spike or when the voltage applied to them exceeds their rated voltage, tantalums do detonate. They are highly susceptible to voltage surges and cannot withstand these conditions without exploding

Typical Applications

Aluminum polymer capacitors provide several benefits for electronic applications due to their structure. This technology is very intriguing for many applications that permit a large ripple current because of its low ESR, low ESL values, and high anticipated lifetime. Polymer capacitors are used in a wide range of applications, including:

  • Power supplies
  • Computer motherboard
  • Domestic appliances
  • Coupling or blocks
  • Smoothing
  • Decoupling or bypass
  • Noise filtering
