Spletaround 20 ppm/°C, and ceramic with a CTE of 10–12 ppm/°C. When this composite structure is 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. SpletCeramic caps topped out around 0.1uF and were the size of three stacked quarters. So it's quite a trick to pack today's hundreds of uFs in a small ceramic package. They have to …

If you see one of these next to a terminal, the capacitor is polarized. Make sure to connect the capacitor's + end to the positive side of the circuit, or the capacitor could eventually cause a short or even explode. [4] If there is no + or -, you can orient the capacitor either way.
