Ceramic Capacitors Ceramic capacitors are one of the most popular and common types of capacitors. In the early days, ceramic capacitors had very low capacitance, but nowadays, this is not the case. Multilayer ceramic capacitors (MLCC) are used extensively in circuits; their capacitance rating can reach hundreds of microfarads (µF).
