Featuring a dominant wavelength of 470nm to 475nm and a peak wavelength of 468nm, this LED delivers consistent blue color output with a typical luminous intensity of 15mcd at just 5mA forward current. The ultra-thin 0.55mm package height makes it particularly suitable for low-clearance and space-constrained designs such as thin-profile consumer electronics, wearable devices, and miniaturized instrumentation. The wide 130-degree viewing angle ensures uniform light distribution across the viewing area. Packaged in the industry-standard 0603 (1608 metric) footprint, the LTST-C191TBKT-5A is compatible with standard surface-mount assembly processes and automated pick-and-place equipment.","working_principle":"The LTST-C191TBKT-5A utilizes an InGaN (Indium Gallium Nitride) semiconductor chip as its light-emitting element. When forward-biased at a typical voltage of 2.8V, electrons in the InGaN active layer recombine with holes at the p-n junction, releasing energy as photons in the blue spectrum with a peak emission at 468nm. The water-clear rectangular lens encapsulates the chip and provides optical coupling with a wide 130-degree half-angle, ensuring broad and even light distribution. The device is designed for continuous operation at up to 20mA forward current, with a peak rating of 100mA for pulsed applications. The spectral line half-width of 25nm indicates a relatively narrow emission band, contributing to the vivid and saturated blue color appearance. Proper ESD handling precautions are recommended during assembly, as InGaN LEDs are sensitive to electrostatic discharge.","pin_description":"
