| Parameter | Value |
|---|---|
Package / Case Physical package or case type of the component, defining its dimensions, mounting style, and thermal characteristics. Common types include SMD, through-hole, BGA, and QFN. Choose the package that fits your PCB layout and assembly process. Verify the exact package code in the datasheet for footprint compatibility. | 3-SIP, SOT-23W |
Operating Temperature Specifies the ambient temperature range within which the component reliably functions. Compare this with your application's thermal environment to ensure proper operation. Always verify against the datasheet for derating curves and maximum ratings. | -40C to 150C |
Lifecycle Status Current stage in the product's lifecycle, such as Active, Obsolete, or End of Life. This indicates availability and long-term supply risk. Check this before designing in a part to ensure it will be available for your product's production lifetime. | Active family reference; verify exact suffix before release |
Sensor Type Specifies the underlying sensing technology, such as optical, inductive, or capacitive. This determines the sensor's operating principle and application suitability. Verify the exact type against the datasheet to ensure compatibility with your target environment and measurement requirements. | Hall-Effect Switch |
Supply Voltage Specifies the nominal operating voltage that must be applied to the component for proper function. Verify this value against your system's power rail and the datasheet's absolute maximum ratings to ensure reliable operation and avoid damage. | 3.8V to 24V |
| Parameter | Value |
|---|---|
Magnetic Threshold Specifies the magnetic flux density at which a sensor output changes state. Compare operating and release points for reliable switching in your application. Verify against the datasheet for temperature and supply voltage variations. | Variant-specific within A110x family |
Function Specifies the logical or operational function of the component, such as switching, amplification, or regulation. This attribute helps identify the device's role in a circuit. Verify the function against the datasheet to ensure it matches your application requirements. | Continuous-Time Unipolar Switch |
