  • Power Cord Types, Power Cable types, Power Plug types

    IEC 60320 power cords uses even number for plug and odd number for the mating receptacle, and usually male appliance inlet is 1 higher than the sheet for the corresponding female cable connector. Therefore the most common used power cord types is C14 to C13 and C20 to C19. Other common power cord types also include C14 to C15 and C20 to C15.

  • Specifications of RF Cables and Applications - RF Page

    2018-6-8u2002·u2002There are mainly two categories of cables in terms of the characteristic impedance. 50 Ohm cables: used in high precision RF test equipments and high frequency applications. 75 Ohm cables: used in domestic video applications, digital audio, TV distribution networks. Impedance of a standard RF cable is independent of its physical length.

  • The Origin of Impedance Matching of 50 ohms in RF Design

    2020-4-9u2002·u2002Around 1922, Bell Laboratory did many experiments and finally found that coaxial cable with the characteristic impedance of 30 ohms and 77 ohms were suitable for this kind of high-power transmissions with low loss. Among them, 30 ohms coaxial cable can transmit the maximum power, and 77 ohms coaxial cable transmission signal loss is the minimum.

    2021-11-12u2002·u2002Speaker cable is the wire used for the electrical connections between speakers and amplifier sources. It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important property to look at. Low-resistance wire allows more of the source's power through to the speaker coil, meaning more power ...

  • The Mysterious 50 Ohm Impedance: Where It Came From

    2021-3-4u2002·u2002The quick answer to this question is that 50 Ohms is the least bad compromise between the impedance corresponding to minimum loss, maximum power, and maximum voltage. Indeed, 50 Ohms is pretty close to the mean between 77 and 30 Ohms, and it's close to 60 Ohms, so it seems natural to assume this is the reason for the 50 Ohm impedance standard.

For example, a one wavelength loop has a feed point impedance of around 120Ω. The geometric mean of 120Ω and 50Ω is 77.5Ω — quite close to the 75Ω impedance of RG-6, RG-59, or RG-11.
