√ Ready to use - ensure correct polarity before installation
√ Long operational life available in hightemperature variants with up to 8000 hours at 105°C [citation:3]
Varies by seller:
Avoid exceeding the rated voltage of 25V this is critical for safety and reliability
Avoid overheating during soldering typical soldering time is ≤5 seconds at ≤260°C
Avoid storing at high temperatures accelerated aging reduces lifetime
