Frequently Asked Questions
What is this LED designed for use in?
It is intended for general display light source usage, but not for functional applications like sensors or optical communication.
How should I handle the product safely during installation?
The product is sensitive to electrostatic discharge; secure countermeasures against ESD and surge/over-voltage are required when handling it.
What determines the maximum allowable forward current?
The permissible forward current must be derated based on the ambient temperature (Ta) used in the application.
Can this LED be used for critical safety equipment?
No. This product is not warranted or intended for usage in applications requiring extraordinarily high reliability, such as medical instruments or traffic signal instruments.
