The SML-D12M1WT86 is a surface-mount device (SMD) LED from ROHM, featuring a compact 0603 package size (1.6x0.8mm, t=0.55mm). This LED emits yellowish-green light with a dominant wavelength range of 569-575nm, making it suitable for a variety of signaling, indicator, and backlighting applications. It operates with a typical forward voltage of 2.2V and is designed for a maximum forward current of 20mA, with peak forward current conditions specified at 100mA (duty 1/10, 1kHz). The LED is characterized by its high luminous intensity and efficiency, with intensity ratings available in various ranks.
The SML-D12M1WT86 is designed with moisture sensitivity level (MSL) 3, indicating that it should be handled with care during the assembly process to prevent moisture-induced damage. Its compact size and low profile make it an ideal choice for space-constrained applications. The LED's performance is supported by ROHM's commitment to quality, ensuring reliable operation and longevity for the end application.
LED
LEDs (Light Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them. They are widely used in various applications due to their efficiency, long life, and compact size. LEDs are available in a range of colors, sizes, and intensities, making them suitable for a wide array of applications including indicator lights, displays, and general illumination.
When selecting an LED, engineers should consider factors such as the desired color (wavelength), luminous intensity, forward voltage, and current requirements. The package size is also important, especially in space-constrained applications. The operating and storage temperature range, as well as the moisture sensitivity level, are crucial for ensuring the reliability and longevity of the LED in the intended application.
LEDs offer several advantages over traditional light sources, including lower energy consumption, longer lifespan, and faster switching. However, they require proper thermal management and current regulation to maintain performance and prevent premature failure. The choice of LED should align with the application's specific requirements, including environmental conditions and desired visual characteristics.
