  • Material

    In electronic components, the parameter "Material" refers to the substance or material used in the construction of the component. The choice of material is crucial as it directly impacts the component's performance, durability, and other characteristics. Different materials have varying properties such as conductivity, resistance to heat, corrosion resistance, and mechanical strength, which determine how the component functions in a circuit. Common materials used in electronic components include metals like copper and aluminum, semiconductors like silicon, insulators like ceramics and plastics, and various alloys. Selecting the appropriate material is essential for designing reliable and efficient electronic components.

    Nylon
  • Series

    In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.

  • Part Status

    Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

    Active
  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures

    Not Applicable
  • Type
    Round Spacer
  • Color
    White
  • Gender

    In the context of electronic components, the parameter "Gender" typically refers to the physical characteristics of connectors or interfaces that determine how they can be mated together. Connectors are often designed with specific gender types, such as male or female, to ensure proper alignment and connection between devices. A male connector typically has protruding pins or plugs that fit into a corresponding female connector, which has receptacles or sockets to receive the pins. This design helps prevent incorrect connections and ensures a secure and reliable electrical connection. Understanding the gender of connectors is crucial when designing or assembling electronic systems to ensure compatibility and proper functionality. It is essential to match the gender of connectors correctly to avoid damage and ensure optimal performance of the electronic components.

    Female, Female
  • Threaded/Unthreaded

    The parameter "Threaded/Unthreaded" in electronic components refers to the type of connection mechanism used for the component. Threaded components have threads on their exterior surface, allowing them to be screwed into place for a secure and stable connection. On the other hand, unthreaded components do not have threads and typically require a different type of connection method, such as soldering or press-fitting.The choice between threaded and unthreaded components depends on the specific application requirements, such as ease of installation, maintenance, and durability. Threaded components are often preferred in applications where frequent disassembly and reassembly are necessary, as they provide a more convenient and reliable connection. Unthreaded components, on the other hand, may be preferred for applications where space constraints or weight considerations are important, as they can offer a more compact and lightweight solution.Overall, understanding the threaded/unthreaded parameter is important for selecting the right electronic components that will best suit the needs of the application in terms of connection method, reliability, and performance.

    Unthreaded
  • Diameter

    In electronic components, the parameter "Diameter" typically refers to the measurement of the width of a circular component, such as a resistor, capacitor, or inductor. It is a crucial dimension that helps determine the physical size and fit of the component within a circuit or on a circuit board. The diameter is usually measured in millimeters (mm) or inches (in) and is important for ensuring proper placement and soldering of the component during assembly. Understanding the diameter of electronic components is essential for selecting the right size for a specific application and ensuring compatibility with other components and the overall design of the circuit.

    3.7338mm
  • Length
    6.35mm
  • Length - Overall

    Length - Overall is a crucial parameter in electronic components that refers to the total length of a component from one end to the other. It encompasses any protruding features or attachments, providing a complete measurement of the component's size. This dimension is essential for determining compatibility with circuit boards, housing, and other components in an assembly. Accurate knowledge of the overall length helps ensure proper fit and function in electronic designs.

    0.250 6.35mm 1/4
  • Diameter - Outside

    The parameter "Diameter - Outside" in electronic components refers to the measurement of the outer diameter of a component. This measurement is crucial for determining the physical size and compatibility of the component with other parts or equipment. It is typically specified in millimeters or inches and helps in ensuring proper fit and alignment during assembly or installation. Understanding the "Diameter - Outside" parameter is important for selecting the right components for a specific application and ensuring optimal performance and functionality of the electronic system.

    0.250 (6.35mm) 1/4
  • Diameter - Inside

    The parameter "Diameter - Inside" in electronic components refers to the measurement of the inner diameter of a component, such as a connector, socket, or housing. This measurement is crucial for ensuring proper fit and compatibility with other components or devices. It helps determine the size of the opening or cavity within the component where other parts or components will be inserted or connected. Understanding the "Diameter - Inside" specification is important for selecting the right components for a specific application and ensuring seamless integration within an electronic system.

    0.147 (3.73mm)
  • Between Board Height

    The parameter "Between Board Height" in electronic components refers to the maximum allowable height between the top surface of the circuit board and the bottom surface of the component that can be mounted on the board. This parameter is crucial for ensuring proper clearance and preventing any interference or short circuits between the component and the board. Manufacturers specify this parameter to ensure that the component fits securely on the board without causing any electrical or mechanical issues. Designers must adhere to this specification during the PCB layout process to guarantee the reliability and functionality of the electronic assembly.

    0.250 6.35mm 1/4
  • RoHS Status

    RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

    RoHS Compliant
  • Lead Free

    Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
