Precautions
- Hall sensors are sensitive devices. Take electrostatic discharge (ESD) protection measures during handling and storage.
- Minimize mechanical stress on the device casing and leads during installation and use.
- Recommended soldering temperature should not exceed [Value Missing], and duration should not exceed [Value Missing] seconds.
- To ensure the safety and stability of the Hall IC, it is not recommended to operate outside the parameter ranges for extended periods.
