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.

Surface Mount
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.

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.

Active
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.

Memory Type

Memory Type refers to the type of memory technology used in an electronic device. It indicates the specific design and architecture of the memory, such as DRAM (Dynamic Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), or Flash memory. Each memory type has unique characteristics, including speed, capacity, volatility, and cost, which determine its suitability for different applications.

SYNCHRONOUS
Clock Frequency

Clock Frequency, measured in Hertz (Hz), is the rate at which an electronic component, such as a microprocessor or oscillator, generates electrical pulses. It determines the speed at which the component can process data and execute instructions. A higher clock frequency generally indicates faster performance, but also higher power consumption and heat generation. Clock Frequency is a crucial parameter for timing-sensitive applications, such as digital signal processing and real-time systems.

400kHz
Access Time

Access time is the time it takes for a memory device to retrieve data from a specific location. It is typically measured in nanoseconds (ns) and is a critical factor in determining the performance of a computer system. The lower the access time, the faster the memory device can retrieve data and the faster the computer can perform tasks.

Memory Format

Memory Format refers to the arrangement and organization of data within a memory device. It specifies the number of bits, bytes, or words stored in each memory location and how they are accessed.

Height

Height, in the context of electronic components, refers to the vertical dimension of the component. It is typically measured in millimeters (mm) or inches (in). Height is an important parameter to consider when designing and assembling electronic circuits, as it affects the overall size and form factor of the device. Components with a smaller height are often preferred for applications where space is limited, such as in portable devices or embedded systems.

1.05mm
Length

Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.
