Wurth Elektronik SMD Aluminium Polymer Capacitor - WCAP-PSLC series. Aluminium 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 range Higher long term stability and expected life No dry out phenomenon due to solid conductive polymer. WCAP-PSLC large capacitance SMD aluminium Polymer series Operating temperature: -55°C to +105°C Low ESR at high frequency range High permissible ripple current Long life and high reliability Load life of 2000h @ +105°C Reflow soldering is recommended
