Dr. René Kalbitz studied physics at the University of Potsdam and at the University of Southampton (GB). After completing his diploma degree, he gained is PhD in the field of organic semiconductors and insulators at the University of Potsdam. He was able to gain further experience in the field of applied research at the Fraunhofer Institute for Applied Polymer Research. He is product manager for supercapacitors at Würth Elektronik since 2018 and oversees research and development projects in the field of capacitors.

All Application Notes by Dr. René Kalbitz

Measured frequency spectrum of a 470 µF aluminum electrolytic capacitor (WCAP-ASLI) for a voltage signal with fundamental frequency of 448.9 Hz. Also shown: the threshold value for audible distortion, as determined in a psychoacoustic experiment for a fundamental frequency of 500 Hz.
