Precaution
Please be careful of the followings
· Soldering temperature: 260°C 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.
