The STW8A12D-E1 is an electronic part with light emitting diodes (LED) SMD RoHS manufactured by SSC. It features a high brightness LED with a 120-degree viewing angle, a built-in current-limiting resistor, and a low forward voltage. The part is RoHS compliant, meaning it does not contain hazardous materials such as lead or cadmium which are common in older electronic components. The SMD (Surface Mount Device) design allows for maximum density and easier mounting than traditional through-hole components, and is RoHS compliant. The STW8A12D-E1 is perfect for applications such as automotive, backlighting, emergency lighting, and display lighting, and is energy efficient and long-lasting.
