The soldering tip temperature should not exceed 300 °C.
Store the LED at 5 °C‑35 °C and 60 % RH for up to one year; if opened for more than a week, re‑condition at 65 °C ± 5 °C for at least 24 hours before use.
The LED can withstand a reverse voltage of up to 5 V.
The bracket must be at least 2 mm away from the colloid before bending.
