Precaution
Please be careful of the following:
1. Soldering temperature: 260 C max.
Soldering time: 5 sec. max.
Soldering portion of lead: up to 1.6 mm from the body of the device
2. The lead can be formed up to 5 mm from the body of the device without forming stress.
Soldering should be performed after the lead forming.
3. Absolute secure counter measures against static electricity and surge should be taken when handling these products. It is
recommended to use wrist band or antistatic gloves when handling these LEDs.
