Wurth Elektronik General Purpose WCAP-PTHT Capacitor Series 125°CAluminium 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-PTHT Series are high temperature polymer electrolytic capacitors Low ESR at high frequency rangeOperating temperature: -55°C to +125°CLoad life of 2000h @ +125°CWave soldering is recommended
