- Mounting Type
The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.
Surface Mount - Package / Case
refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.
14-UFBGA, WLCSP - Supplier Device Package
The parameter "Supplier Device Package" in electronic components refers to the physical packaging or housing of the component as provided by the supplier. It specifies the form factor, dimensions, and layout of the component, which are crucial for compatibility and integration into electronic circuits and systems. The supplier device package information typically includes details such as the package type (e.g., DIP, SOP, QFN), number of pins, pitch, and overall size, allowing engineers and designers to select the appropriate component for their specific application requirements. Understanding the supplier device package is essential for proper component selection, placement, and soldering during the manufacturing process to ensure optimal performance and reliability of the electronic system.
14-WLCSP (1.59x1.59) - Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
-30°C~85°C TA - Packaging
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

- Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Not For New Designs - 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
1 (Unlimited) - Voltage - Supply
Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.
2.4V~3.6V - Current - Supply (Max)
The parameter "Current - Supply (Max)" in electronic components refers to the maximum amount of current that a component can draw from a power supply for its operation. This parameter is critical for ensuring that the power supply can adequately meet the demands of the component without causing damage or malfunction. Exceeding this specified maximum current can lead to overheating, reduced performance, or failure of the component. It is essential to consider this value when designing or integrating components into electronic circuits to maintain reliability and functionality.
10mA - Output Type
The "Output Type" parameter in electronic components refers to the type of signal or data that is produced by the component as an output. This parameter specifies the nature of the output signal, such as analog or digital, and can also include details about the voltage levels, current levels, frequency, and other characteristics of the output signal. Understanding the output type of a component is crucial for ensuring compatibility with other components in a circuit or system, as well as for determining how the output signal can be utilized or processed further. In summary, the output type parameter provides essential information about the nature of the signal that is generated by the electronic component as its output.
I2C, SPI - Resolution
Resolution in electronic components refers to the smallest increment of measurement or change that can be detected or represented by the component. It is a crucial specification in devices such as sensors, displays, and converters, as it determines the level of detail or accuracy that can be achieved. For example, in a digital camera, resolution refers to the number of pixels that make up an image, with higher resolution indicating a greater level of detail. In analog-to-digital converters, resolution is the number of discrete values that can be represented in the digital output, determining the precision of the conversion process. Overall, resolution plays a significant role in determining the performance and capabilities of electronic components in various applications.
16 b - Sensing Range
The sensing range of position sensors is the displacement between the sensing face of the sensor and the approaching measurement object that triggers a signal change in the sensor.
±4.9mT - Axis
In electronic components, the parameter "Axis" typically refers to the orientation or direction along which a specific characteristic or measurement is being considered. For example, in a sensor or accelerometer, the axis may indicate the direction in which the device is measuring acceleration. In a motor or actuator, the axis may refer to the direction of movement or rotation.Understanding the axis of a component is crucial for proper installation, calibration, and operation. It helps in determining how the component will interact with other parts of a system and how its performance can be optimized. Different components may have multiple axes to consider, especially in complex systems where movement or measurements occur in multiple directions.Overall, the axis parameter provides important information about the spatial orientation or directionality of an electronic component, guiding engineers and technicians in effectively utilizing the component within a larger system.
X, Y, Z - Features
In the context of electronic components, the term "Features" typically refers to the specific characteristics or functionalities that a particular component offers. These features can vary depending on the type of component and its intended use. For example, a microcontroller may have features such as built-in memory, analog-to-digital converters, and communication interfaces like UART or SPI.When evaluating electronic components, understanding their features is crucial in determining whether they meet the requirements of a particular project or application. Engineers and designers often look at features such as operating voltage, speed, power consumption, and communication protocols to ensure compatibility and optimal performance.In summary, the "Features" parameter in electronic components describes the unique attributes and capabilities that differentiate one component from another, helping users make informed decisions when selecting components for their electronic designs.
