Up to 50 Years Life

SPA SMT capacitors are polarized, aluminum capacitors tantalum which can fail short and burn, SPA capacitors which use a highly conductive solid polymer as the gradually become open circuits after 25 to 50 years electrolyte. They have reliabilityadvantages over both operation. aluminum and solid tantalum electrolytic capacitors. Unlike aluminum capacitors,there is no liquid electrolyte Life expectancy curves show 200,000 hours expected life that can evaporate and cause a failure. Unlike solid at full rated voltage and normal ambient conditions.

Ultra Low E.S.R. and High Rippled Current Capability

The equivalent series resistance (e.s.r.) of solid polymer The series resistance of electrolytic capacitors is largely aluminum capacitors is much lower than the e.s.r. of solid determined by the resistivity of the electrolyte. Because tantalum capacitors. This results in a much higher ripple the resistivity of SPA’s polymer electrolyte is several current handling capability. The e.s.r. is even lower than orders of magnitude less than that of other electrolytes, the new tantalum polymer hybrid capacitors. SPA’ s ultra- the equivalent series resistance is almost zero. low resistance magic is in the solid conductive polymer.

Construction

Construction is a unique combination of the elements of pentoxide which is built upon a tantalum pellet anode. aluminum electrolytic and solid tantalum capacitors. A highly conductive polymer electrolyte film is deposited over the aluminum oxide dielectric in SPA capacitors. Like conventional aluminum electrolytic capacitors, Carbon and silver paint are used to finish the capacitor's the anode in SPA capacitors is an aluminum plate on cathode. This is similar to what is used in solid tantalum which an aluminum oxide layer has been built up by capacitors, where manganese dioxide is used as the an electrolysis process. The aluminum oxide serves as electrolyte. the dielectric in both SPA and conventional aluminum electrolytics. The capacitor element is encased in a molded resin that is capable of meeting the UL-94,V0 flammability rating. The dielectric in solid tantalum capacitors is tantalum The terminals are solder coated copper clad steel.
