Surface-mount capacitor A MOSFET, placed upon a British postage stamp for size comparison. Surface-mount technology (SMT), originally called planar mounting, [1] is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). [2]
IEC/EN 60384-20—Fixed metallized polyphenylene sulfide film dielectric surface mount d.c. capacitors; IEC/EN 60384-23—Fixed metallized polyethylene naphthalate film dielectric chip d.c. capacitors; Electrolytic capacitors. IEC/EN 60384-3—Surface mount fixed tantalum electrolytic capacitors with manganese dioxide solid electrolyte
The codes given in the chart below usually tell the length and width of the components in tenths of millimeters or hundredths of inches. For example, a metric 2520 component is 2.5 mm by 2.0 mm which corresponds roughly to 0.10 inches by 0.08 inches (hence, imperial size is 1008).
A typical ceramic through-hole capacitor. A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
For example, a 220 μF 6 V capacitor will have a surface area close to 346 cm 2, or 80% of the size of a sheet of paper (US Letter, 8.5×11 inch paper has area ~413 cm 2), although the total volume of the pellet is only about 0.0016 cm 3.
Surface mount components avoid undesirable high-frequency effects due to the leads and simplify automated assembly, although manual handling is made difficult due to their small size. Mechanically controlled variable capacitors allow the plate spacing to be adjusted, for example by rotating or sliding a set of movable plates into alignment with ...
Tantalum electrolytic capacitors, usually used in the SMD (surface-mount device) version, have a higher specific capacitance than the aluminium electrolytic capacitors and are used in devices with limited space or flat design such as laptops. They are also used in military technology, mostly in axial style, hermetically sealed.
