WS2812B LED Intelligent control LED integrated light source WORLDSEMI CO.,LIMITED WS2812B Datasheet and Specifications Intelligent control LED integrated light source Jan,2016 V1.
WS2812B LED Intelligent control LED integrated light source Features and Benefits Intelligent reverse connect protection, the power supply reverse connection does not damage the IC. The control circuit and the LED share the only power source. Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.

WS2812B LED Intelligent control LED integrated light source WS2812B Products Using Instructions MSL=5A Level 1. Purpose： WS2812B-Mini LED lamp’s surface use the high hardness silicone resin,can ensure that no matter customers use PU glue or epoxy resin to do the silicone drop rubber processing,won’t lead the LED to die;also has a very good anti sulfide capacity.
WS2812B LED Intelligent control LED integrated light source electric soldering iron’s temperature being not higher than 350 ℃ , every time when welding electric iron in the bracket pin,stay time shall be no more than 3 seconds,if requiring repeat welding,then interval time shall be no less than 2 seconds.
WS2812B LED Intelligent control LED integrated light source leakage phenomenon,Please use directly, can don’t do the bake dehumidification. 2. During use, please open a bag and use a bag,please don’t open many bags at one-time which shall lead the LEDs absorb moisture in the air since you don’t use them at once. 3. After SMT,please do the reflow soldering furnace immediately,please don’t leave them in in the pre-reflow for a long time which absorb moisture.
