  2. SMB connector - Wikipedia

    en.wikipedia.org/wiki/SMB_connector

    SMB (SubMiniature version B) connectors are coaxial RF connectors developed in the 1960s. SMB connectors are smaller than SMA connectors.. They feature a snap-on coupling and are available in either 50 Ω or 75 Ω impedance.

  3. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  4. Bus coupler - Wikipedia

    en.wikipedia.org/wiki/Bus_coupler

    A dual-terminated coupler (with or without non-functional bus connectors) can be employed where the coupler acts as the bus without other couplers. RFI dust caps (with or without safety chains) are recommended for all unused stub ports. Data bus couplers are readily available in 2 through 8 stubs and in various sizes and shapes of boxes and ...

  5. SMA connector - Wikipedia

    en.wikipedia.org/wiki/SMA_connector

    The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.

    Calling them "sub-miniature" was appropriate when they were first introduced, but today they are among the largest common connectors used in computers. The DB25 is used for multi-track recording and other multi-channel audio, analog or digital ( ADAT interface (DB25)), and was the standard connector for IBM compatible PC printer connection ...

  8. Twin-lead - Wikipedia

    en.wikipedia.org/wiki/Twin-lead

    The characteristic impedance of twin lead is a function of the insulating material and its thickness, and the wire diameter and its spacing; in the most common type, 300 Ω twin-lead ribbon cable, the wire is usually AWG 20 or 22 (0.52 or 0.33 mm²), about 7.5 millimetres (0.30 in) apart.

  9. Duality (electrical circuits) - Wikipedia

    en.wikipedia.org/wiki/Duality_(electrical_circuits)

    A dual of a relationship is formed by interchanging voltage and current in an expression. The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the duality of electricity and magnetism. Here is a partial list of electrical dualities: voltage – current
