Precaution
* * * Please be careful of the followings Soldering temperature: 260C max Soldering time : 3 s max
(soldering portion of lead: Up to 2 mm from the body of the device) If the lead is formed, the lead should be formed up to 5 mm from the body of the device without forming stress to the resin. Soldering should be performed after lead forming. This visible LED lamp also emits some IR light. If a photodetector is located near the LED lamp, please ensure that it will not be affected by this IR light.
