Customer ServiceWhen a capacitor is polarised, it will have two terminals, and they are known as anode and cathode. These terminals are considered while connecting them in a circuit. Whereas when the capacitor is non-polarized, there is terminal involved and therefore can be used in either way.
Customer ServiceMultilayer ceramic capacitors (MLCC) have wide application in electronic due to its electrical characteristics: low equivalent series resistance (ESR) and high volume efficiency.
Customer Serviceis heated, the electrodes tend to force the capacitor apart. This tendency is made worse by Ag/Pd being a much better conductor of heat (>400 W/m.K) than ceramic (4–5 W/m.K), so that a thermal gradient will exist across the ceramic layer. The solder terminations also expand at a greater rate (25–30 ppm/°C) than the ceramic part and
