WebWikipedia - tantalum capacitors. Most tantalum capacitors are polarized devices, with distinctly marked positive and negative terminals. When subjected to reversed polarity (even briefly), the capacitor depolarizes and the dielectric oxide layer breaks down, which can cause it to fail even when later operated with correct polarity. WebCase codes are most often seen with tantalum capacitors. Case size codes are based on the sizes in 0.01s of an inch in English and 0.1 mm in metric. Example: Case code 0603 (EIA English) and 1608 (IEC metric) is .063 x .031" in English and 1.6 x .8 mm in metric.
