Information technology infrastructures have a little-known weak link: The capacitors in their power supplies.
Conventional electrolytic capacitors tend to fail prematurely when their liquid electrolyte dries up‚ which happens in response to elevated temperatures and long on times.
Conventional tantalum capacitors are one possible solution to these premature failures. However, tantalums require voltage derating to avoid a very undesirable failure mode— namely, the potential for fires.
More advanced polymer-based capacitors have emerged as a way to improve lifecycle and reliability of IT equipment such as servers, switches, routers and modems.
Polymer wound capacitors such as OS-CON do not have a liquid electrolyte and therefore can have extremely long life.
POSCAP polymer-tantalum capacitors contain no oxygen in their formulation. So they are not prone to combustion upon failure. SP-Caps also have a similar benign failure mode.
All three families of advanced capacitor also offer the features required for information infrastructure:
- Compact size
- Low ESR
- High Ripple Current
- Long Life
