Wurth Elektronik SMD Aluminium Polymer Capacitor - WCAP-PSLP seriesAluminium Polymer capacitors contain solid conductive polymer instead of wet electrolytic,thus the benefits are: High permissible ripple current due to lower ESR at high frequency rangeHigher long term stability and expected lifeNo dry out phenomenon due to solid conductive polymerWCAP-PSLP are low profile SMD polymer electrolytic capacitors SeriesLoad life of 2000h @ +105°COperating temperature: -55°C to +105°CReflow soldering is recommended
