New Release: 3535 and 4545 Ultraviolet UVC LED Series (Low, Mid, and High Power)

QTB is delighted to announce the release of the Ultraviolet UVC SMD LED series, with a variety of electrical and optical properties to select from. Drive current options start as low as 20mA and go up as high as 350mA. Two separate ranges of wavelengths are offered as standard from 260nm to 270nm and 270nm to 285nm. Such options provide more design flexibility and consistency that are required in new, emerging applications such as Ultraviolet Germicidal Irradiation (UVGI). To ensure reliability and performance, the entire 3535 and 4545 Ultraviolet UVC LED series feature ceramic structures, glass lens, and ESD production devices. The blend of available options and robust designs makes these series, perfect candidates for disinfection and sterilization.
