0805 Dual-color SMD LED Wholesales, Price, Sales, Manufacturer's Phone Number [Nanjing Wanshi Bo Electronic Co., Ltd.] 1. Through-hole small power specifications include: Straw Hat/Cap, Round Head, Concave, Elliptical, Square (2*3*4) Sub-head, Flat Head, (3/5/Flat Head/Bread Type) Piranha, etc. 2. SMD surface-mount LEDs are generally categorized as (3020/3528/5050, these are top-lighting) and 1016/1024, which are side-lighting sources. 3. High-power LEDs cannot be classified as surface-mount series, as they have different power and current consumption, and their photoelectric parameters vary greatly. A single high-power LED light source without a heat sink base (usually a hexagonal aluminum base) has little difference in appearance from a standard surface-mount, but the high-power LED light source is round and the packaging method is essentially the same as SMD surface-mounts. However, there are fundamental differences in usage conditions, environment, and effects between them.
