Harvatek B1931USD Red LED Precaution for Use:
1、The chips should not be used directly in any type of fluid such as water, oil, organic solvent, etc.
2、When the LEDs are illuminating, the maximum ambient temperature should be first considered before operation.
3、LEDs must be stored in a clean environment. A sealed container with a nitrogen atmosphere is necessary if the storage period is over 3 months after shipping.
4、The LEDs must be used within 72 hours after unpacked. Unused products must be repacked in an anti-electrostatic package, folded to close any opening and then stored in a dry and cool space.
5、The appearance and specifications of the products may be modified for improvement without further notice.
6、The LEDs are sensitive to the static electricity and surge. It is strongly recommended to use a grounded wrist band and anti-electrostatic glove when handling the LEDs.If a voltage over the absolute maximum rating is applied to LEDs, it will damage LEDs.Damaged LEDs will show some abnormal characteristics such as remarkable increase of leak current, lower turn-on voltage and getting unlit at low current.
