Whether you are an engineer with enough experience to be called a graybeard or a novice that keeps grabbing the wrong end of a soldering iron, there is one component that eludes everyone working in electronics.
It’s the humble capacitor.
A seemingly simple device, turns out, to be incredibly complex. While the basic electrode-dielectric-electrode structure sounds simple, the materials used in that structure drastically changes the characteristics of the device.

There’s a new website created by KEMET Electronics which aims to educate all levels of engineers about the ins and outs of capacitors. They call it the KEMET Engineering Center.
November 2013’s issue of Electronic Products features an article on the cover titled “Introduction to Polymer Capacitors.” The author is, well, me. This article explains the differences between traditional MnO2-Tantalum and Polymer-Tantalum capacitors. Previously I explained these differences in the post on the fire hazard the Arduino GSM shield poses (due to improper derating).
You can find the Electronic Products article wherever magazines are sold or here: Introduction to Polymer Capacitors. Check below for links to high-resolution pictures.
