Wurth Elektronik 33μF Through Hole Polymer Capacitor, 50V 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-PTHR is a high reliability polymer electrolytic capacitor series
Low ESR at high frequency range
High permissible ripple current
Load life of 2000h @ +105°C
Operating temperature: -55°C to +105°C
Wave soldering is recommended

Solid Radial 105°C
