Wurth Elektronik 330μF Surface Mount Polymer Capacitor, 16V dc

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
