SMLD12WBN1W Mini-Mold Chip LED
ROHM Semiconductor's white chip LED features small size and world-class reliability
ROHM Semiconductor's SMLD12WBN1W is a white chip LED with 1608 (1.6 mm x 0.8 mm) size that achieves class-leading reliability. This package offers superior mountability and long operational life, which makes it ideal for use in display panels (e.g., temperature control displays), industrial, and compact consumer equipment.
High-reliability LEDs are required to guarantee no degradation in luminosity, even with continuous operation for over ten years. However, achieving this has not been possible until now due to the use of epoxy or silicone resins for molding of typical white chip LEDs. These types of material could not provide enough reliability to prevent degradation in luminosity or provide enough package strength to facilitate mounting on circuit boards.
ROHM has been providing 1608-size chip LEDs in colors ranging from red to green, and now it is adding white to this product range to meet market demand. The adoption of a material that combines the benefits of epoxy and silicone resins made it possible to achieve class-leading reliability of white chip LED in such a small package.
