The DIALIGHT 551-3103F is a 3mm CBI (Circuit Board Indicator) LED designed for robust and reliable performance in various industrial applications. Its high-contrast design ensures excellent visibility, while the UL 94 V-0 rated housing provides enhanced safety. The CBI features housing stand-offs for easy PCB cleaning and locating pins for stability during soldering. It's suitable for creating horizontal LED arrays and is commonly used in indicator panels and control systems. Reverse polarity options are available by adding -010 to the part number.
