Overview of LMR300

The Times Microwave LMR®-300 5/16 in low loss coaxial cable performs similarly to corrugated copper cables, but with more flexibility and a simpler connection. This 50 Ohm coaxial cable has a bare copper center conductor and a stranded outside conductor for a 1 in bending radius. The use of a shield that is 90% braided results in a minimal loss. Polyethylene foam provides insulation.

  • Mount

    In electronic components, the term "Mount" typically refers to the method or process of physically attaching or fixing a component onto a circuit board or other electronic device. This can involve soldering, adhesive bonding, or other techniques to secure the component in place. The mounting process is crucial for ensuring proper electrical connections and mechanical stability within the electronic system. Different components may have specific mounting requirements based on their size, shape, and function, and manufacturers provide guidelines for proper mounting procedures to ensure optimal performance and reliability of the electronic device.

    Foam Polyethylene (FPE)
  • Conductor Material

    A conductor is a material which contains movable electric charges. In metallic conductors, such as copper or aluminum, the movable charged particles are electrons, though in other cases they can be ions or other positively charged species.

    Copper, Bare
  • Jacket (Insulation) Material

    The parameter "Jacket (Insulation) Material" in electronic components refers to the material used to cover and protect the internal components of a cable or wire. This material provides insulation to prevent electrical interference, short circuits, and damage from environmental factors such as moisture, heat, and chemicals. Common jacket materials include PVC (polyvinyl chloride), Teflon, rubber, and polyethylene. The choice of jacket material depends on the specific application requirements, such as temperature range, flexibility, and resistance to abrasion. Selecting the appropriate jacket material is crucial for ensuring the reliability and longevity of the electronic component in its intended operating conditions.

    Polyethylene (PE)
  • Shield Material

    Shield Material in electronic components refers to the material used to create a shield or barrier that protects the component from electromagnetic interference (EMI) or radio frequency interference (RFI). The shield material is typically a conductive material such as copper or aluminum that is capable of blocking or absorbing unwanted electromagnetic signals. By using the appropriate shield material, electronic components can maintain their performance and reliability in environments where EMI or RFI may be present. The effectiveness of the shield material is crucial in ensuring the proper functioning of electronic devices and preventing interference from external sources.

  • Jacket Color

    The parameter "Jacket Color" in electronic components refers to the color of the protective outer layer that encases wires, cables, or other electronic components. This color can indicate specific attributes such as the type of insulation material, intended use, or compliance with certain standards. Different colors might be used to distinguish between various types of signals, voltage levels, or applications, providing a visual means of identifying components in a system. Additionally, the jacket color can also influence heat dissipation and aesthetic appeal in electronic assemblies.

  • Conductor Strand

    Stranded conductors are composed of uninsulated “strands” of wire twisted together. The advantages of conductor stranding over a single strand of equal cross-section are increased flexibility and flex-fatigue life.

    Solid
  • Jacket (Insulation) Diameter

    The "Jacket (Insulation) Diameter" parameter in electronic components refers to the outer diameter of the insulation or protective jacket surrounding a wire or cable. This measurement is important for determining the overall size and compatibility of the component within a system or circuit. A larger jacket diameter may provide better protection against environmental factors and mechanical stress, while a smaller diameter may be more flexible and space-saving. It is crucial to consider the jacket diameter when selecting and installing electronic components to ensure proper fit and functionality.

  • Shield Type

    Shield Type in electronic components refers to the method used to protect sensitive circuits from electromagnetic interference (EMI) and radio frequency interference (RFI). It encompasses the materials and techniques employed to create barriers around wires, circuits, or devices, which may include metallic enclosures, conductive coatings, or grounding practices. The choice of shield type can significantly impact the performance and reliability of electronic systems, especially in environments with high levels of interference.

    Foil, Braid
  • Dielectric Diameter

    Dielectric diameter is a parameter used in electronic components, particularly in capacitors. It refers to the physical size of the dielectric material within the capacitor. The dielectric material is an insulating substance that separates the two conductive plates of the capacitor. The dielectric diameter is important because it affects the capacitance value and performance of the capacitor. A larger dielectric diameter typically results in a higher capacitance value and better insulation properties. Manufacturers specify the dielectric diameter to ensure proper functioning of the capacitor in electronic circuits.

    0.190 (4.83mm)
  • VoP, Velocity of Propagation

    The Velocity of Propagation (VoP) is a parameter used to describe the speed at which an electrical signal travels through a medium, such as a cable or transmission line, in electronic components. It is typically expressed as a percentage of the speed of light in a vacuum. A higher VoP indicates that the signal propagates faster through the medium, which can affect the overall performance of the electronic system. VoP is an important consideration in designing and analyzing high-speed digital communication systems to ensure signal integrity and minimize signal distortion. It is also used in determining the delay characteristics of signals in transmission lines and is a key factor in determining the maximum operating frequency of a system.
