  2. Surface-mount technology - Wikipedia

    en.wikipedia.org/wiki/Surface-mount_technology

    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]

  3. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    Comparing the capacitors from the table with a supercapacitor, the highest energy density capacitor family. For this, the capacitor 25 F/2.3 V in dimensions D × H = 16 mm × 26 mm from Maxwell HC Series, compared with the electrolytic capacitor of approximately equal size in the table.

  4. List of electronic component packaging types - Wikipedia

    en.wikipedia.org/wiki/List_of_electronic...

    Chip-size package (CSP) developed by National Semiconductor [21] COB: Chip on board: Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a ...

  5. Ceramic capacitor - Wikipedia

    en.wikipedia.org/wiki/Ceramic_capacitor

    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.

  6. Aluminum electrolytic capacitor - Wikipedia

    en.wikipedia.org/.../Aluminum_electrolytic_capacitor

    The electrolyte, which serves as cathode of the capacitor, covers the etched rough structure of the oxide layer on the anode perfectly and makes the increased anode surface effectual. After impregnation the impregnated winding is mounted in an aluminum case and sealed.

  7. Electrolytic capacitor - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_capacitor

    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.

  8. Polymer capacitor - Wikipedia

    en.wikipedia.org/wiki/Polymer_capacitor

    Polymer SMD Tantalum Electrolytic Capacitors are available up to a size of 7.3x4.3x4.3 mm (length × width × height) with a capacity of 1000 μF at 2.5 V. They cover temperature ranges from −55 °C to +125 °C and are available in rated voltage values from 2.5 to 63 V.

  9. Table tennis racket - Wikipedia

    en.wikipedia.org/wiki/Table_tennis_racket

    Table tennis regulations approved by the International Table Tennis Federation (ITTF) allow different surfaces on each side of the paddle for varying amount of spin (including nullifying it) or speed. [2] For example, a player may have a spin-heavy rubber on one side of their paddle, and no spin on the other side.
