Results: Capacitance temperature dependence  The first thing that I wanted to test was how the temperature affects the capacitance of the different capacitors. I performed a temperature sweep from ambient temperature to ~80 °C, and then back to ambient temperature.   It can be seen that the temperature curve looks like a stairway at higher temperatures, this was caused by the lack of precision of the MyDAQ ohmmeter. The temperature curve was not identical in all 3 measurements ...
Introduction  Ideal capacitors can be defined with the following simple equation:   In this design challenge I will explore parasitic elements of polymer capacitors that are not modeled by the previous equation, in particular I will explore how temperature affects the capacitance and leakage current, and the dielectric absorption of 3 types of polymer capacitors.     Experimental methods  I received 17 different polymer capacitors, from them I selected 3 different t ...
