  • Mount
    Through Hole
  • Mounting Type

    Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include: * Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side. * Surface-mount: Component is placed on the surface of the PCB and soldered in place. * Press-fit: Component is pressed into place on the PCB without soldering. * Socket: Component is inserted into a socket on the PCB, allowing for easy replacement. The mounting type is determined by factors such as the component's size, shape, and power requirements.

  • Package / Case

    Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

    32-DIP Module (0.600, 15.24mm)
  • Number of Pins

    Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

  • Operating Temperature

    Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

  • Part Status

    Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

    Obsolete
  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

  • Technology

    Technology, in the context of electronic components, refers to the specific manufacturing process and materials used to create the component. It encompasses the semiconductor fabrication techniques, such as the type of transistor used (e.g., MOSFET, BJT), the gate oxide thickness, and the interconnect materials. Technology also includes the packaging type, such as surface mount or through-hole, and the leadframe or substrate material. The technology used impacts the component's performance characteristics, such as speed, power consumption, and reliability.

  • Supply Voltage

    Supply Voltage is the voltage required to power an electronic component. It is typically measured in volts (V) and is specified in the component's datasheet. The supply voltage must be within the specified range for the component to function properly. If the supply voltage is too low, the component may not function at all. If the supply voltage is too high, the component may be damaged.

  • Interface

    In electronics, an interface refers to the connection point or boundary between two or more electronic systems or devices. It defines the physical, electrical, and logical characteristics that enable communication and data exchange between them. An interface specifies the protocols, pinouts, voltage levels, data formats, and other parameters necessary for the systems to interact seamlessly. It ensures compatibility and interoperability between different components or devices, allowing them to exchange information and perform their intended functions.

  • Time Format

    Time Format is an electronic component parameter that specifies the format of the time data that is output by the component. The most common time formats are 24-hour format and 12-hour format. 24-hour format displays the time in hours and minutes, with the hours ranging from 00 to 23. 12-hour format displays the time in hours, minutes, and seconds, with the hours ranging from 01 to 12 and an AM or PM designation.

    HH:MM:SS (24 hr)
  • Date Format

    Date Format is an electronic component parameter that specifies the format in which the date is displayed on the component. This parameter is typically used for components that have a built-in clock or calendar, such as digital watches, clocks, and computers. The Date Format parameter can be set to a variety of different formats, such as MM/DD/YY, DD/MM/YY, and YYYY/MM/DD.
