Notes:
- Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
- The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
- Typical Electrical / Optical Characteristics Curves
- Please read the following notes before using the datasheets:
1. Over-current-proof
Customer must apply resistors for protection, otherwise slight voltage shift will
cause big current change ( Burn out will happen ).
2. Storage
2.1 Do not open moisture proof bag before the products are ready to use.
2.2 Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less.
2.3 The LEDs should be used within a year.
2.4 After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.
3. Soldering Condition
3.1 Pb-free solder temperature profile.
3.2 Reflow soldering should not be done more than two times.
4. Soldering Iron
Each terminal is to go to the tip of soldering iron temperature less than 260℃ for 5 seconds
within once in less than the soldering iron capacity 25W. Leave two seconds and more
intervals, and do soldering of each terminal. Be careful because the
damage of the product is often started at the time of the hand solder.
5. Repairing
Repair should not be done after the LEDs have been soldered. When repairing is unavoidable,
a double-head soldering iron should be used. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
