An aluminum electrolytic capacitor comprises four separate layers: an aluminum foil cathode; an electrolyte-soaked paper separator; an aluminum anode which has been chemically treated to form a very thin aluminum oxide layer; and finally, another paper separator. This assemblage is then rolled and placed in a sealed metallic can.
The circuit model of a capacitor consists of a series resistive element representing the ohmic resistance of the conducting elements along with the dielectric resistance. This is called the equivalent, or effective, series resistance (ESR). The dielectric effects occur when AC signals are applied to the capacitor.
These capacitors use a ceramic dielectric. There are two classes of ceramic capacitors, Class 1 and Class 2. Class 1 is based on para-electric ceramics like titanium dioxide. Ceramic capacitors in this class have a high level of stability, good temperature coefficient of capacitance, and low loss.
Capacitors are available in a variety of physical mounting configurations, including axial, radial, and surface mount (Figure 2). Figure 2: Capacitor mounting, or configuration types include axial, radial, and surface mount. Surface mount is very widely used at this time. (Image source: DigiKey)
Film capacitors come in many forms: Polypropylene (PP): These have particularly good tolerance and stability with low ESR and ESL and high voltage breakdown ratings. Due to temperature limits of the dielectric they are available only as leaded devices.
Suitable for precision-tuned circuits due to the extreme stability in the 0°C thru +50°C range and it has long-term stability. The dielectric has a maximum operating temperature of +85°C. It will melt at +100°C. Metalized polyester foil. Known as Mylar, Polyester or Polyethylene terephthalate PET capacitors.
