Latest polymer capacitor alternatives offer a variety of new options

Wurth Elektronik's WCAP-PSHP series SMD aluminium polymer capacitors are now available from Farnell element14. They contain solid conductive polymer instead of wet aluminium electrolytic, with ESR values below 10mohm. The WCAP-PSHP series is the outcome of a general trend among aluminium capacitor manufacturers to develop new polymer alternatives that offer customers a variety of new options, i.e. higher permissible ripple current due to lower ESR at high frequencies, higher long-term stability and lifetime, and no drying-out issues. Reflow soldering is recommended, says the company.
