The recommended operating temperature range for the SFH 485-3 is -40°C to 100°C, although it can withstand storage temperatures between -40°C and 125°C.
To ensure proper soldering, use a soldering iron with a temperature of 250°C to 260°C, and apply a soldering time of 2-3 seconds. Also, make sure the PCB is designed with a suitable land pattern and thermal relief to prevent thermal damage.
The maximum allowable voltage for the SFH 485-3 is 5.5V, although the recommended operating voltage is 3.3V or 5V. Exceeding the maximum voltage can lead to device damage or failure.
Yes, the SFH 485-3 is designed to operate in humid environments, but it's essential to follow proper handling and storage procedures to prevent moisture-related issues. Siemens recommends storing the devices in a dry, clean environment with a relative humidity below 60%.
To troubleshoot issues with the SFH 485-3, start by checking the device's pinout and ensuring proper connections. Verify the power supply voltage and check for any signs of physical damage or overheating. If the issue persists, consult the datasheet or contact Siemens support for further assistance.
