NICHICON Launches the PCA Series ofChip-Type Conductive Polymer Aluminum Solid Electrolytic Capacitors(Guaranteed at an Industry-High 125°C with SuperimposedHigh Ripple Tolerance)
NICHICON CORPORATION has launched the PCA Series of chip-type conductive polymer aluminum solid
electrolytic capacitors for use in automotive and industrial equipment environments requiring the high reliability.
The PCA Series has the same ESR and other characteristics as the current PCR Series at 125℃, and has
improved the ripple current, achieving industry-leading ripple current capability at 125℃.

Overview and Development BackgroundPreviously, we have marketed our PCR Series of chip-type conductive polymer aluminum solid electrolytic
capacitors in sectors demanding high reliability, such as automotive, industrial equipment, andtelecommunications. In recent years, the demand for the high maximum ripple current durability has been
growing along with the use of electronic components in automobiles. To satisfy this demand, we launched thePCA Series having a higher maximum ripple current than the PCR Series.

Features
The PCA series achieves high ripple tolerance while maintaining the same ESR performance and othercharacteristics as the current PCR series. This is made possible by improvements to our existing
technologies for heat resistance and ripple tolerance in conductive polymer aluminum solid electrolytic
capacitors, and by further optimization of the conductive polymer formation method, componentcomposition, and material design. Further, the series offers the industry’s first conductive polymer aluminum
solid electrolytic capacitors with rated voltages of 25–63V that are guaranteed with superimposed high ripple
tolerance. The resultant higher ripple tolerance in capacitors of the same size contributes to more compact

terminals by reducing the number of capacitors needed.
