UV SMD LED with Silicone Lens VLMU52-...-14 DESCRIPTION The VLMU52-...-14 series comprises 3 high brightness UV LED types within an overall wavelength range from 38nm to 41nm. The ceramic based high power package with silicone lens features a good longterm stability against thermal exposure and UV light irradiation and therefore a long life time. The package size is 5.2 mm x 5.2 mm x 3.1 mm, and the radiant power up to 44 mw at 7 ma, with 4 LED chips connected in series. PRODUCT GROUP AND PACKAGE DATA Product group: LED Package: SMD ceramic high power Product series: high power UV LED Angle of half intensity: ± 7 Lead-finishing: Au SAFETY ADVICES Depending on the mode of operation, these devices emit highly concentrated non visible ultraviolet light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 62471 Photobiological Safety of Lamp and Lamp Systems.

A secondary cardboard box is used for shipping purposes. RECOMMENDED METHOD OF STORAGE Dry box storage is recommended as soon as the aluminum bag has been opened to prevent moisture absorption. The following conditions should be observed, if dry boxes are not available: Storage temperature 1 C to 3 C Storage humidity 6 % RH max. After more than 1 year under these conditions moisture content will be too high for reflow soldering. In case of moisture absorption, the devices will recover to the former condition by drying under the following condition: 192 h at 4 C + 5 C / - C and < 5 % RH (dry air / nitrogen) or 24 h at 6 C + 5 C and < 5 % RH for all device containers or 24 h at C + 5 C not suitable for reel or tubes.
