Data Sheet 1206 Package Chip Infrared LED With Inner Lens IR11-21C/TR8 Precautions For Use
1. Over-current-proof Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (Burn out will happen). 2. Storage 2.1 Do not open moisture proof bag before the products are ready to use. 2.2 Before opening the package, the Photodiode should be kept at 10℃~30℃ and 90%RH or less. 2.3 The Photodiode suggested be used within one year. 2.4 After opening the package, the devices must be stored at 10°C~30°C and  60%RH, and used within 168 hours (floor life). If unused Photodiode remain, it should be stored in moisture proof packages. 2.5 If the moisture absorbent material (desiccant material) has faded or unopened bag has exceeded the shelf life or devices (out of bag) have exceeded the floor life, baking treatment is required. 2.6 If baking is required, refer to IPC/JEDEC J-STD-033 for bake procedure or recommend the following conditions: 96 hours at 60°C ± 5°C and < 5 % RH (reeled/tubed/loose units) 3. Soldering Condition 3.1 Lead solder temperature profile 3.2 Reflow soldering should not be done more than two times. 3.3 When soldering, do not put stress on the LEDs during heating. 3.4 After soldering, do not warp the circuit board. 6 Copyright © 2015, Everlight All Rights Reserved.
