5 mm Oval Red LED
Stock Quantity: 0
The LL2508TLHR4-A02, manufactured by LEDMAN OPTOELECTRONIC CO .LTD, is a 5mm oval-shaped LED emitting in the red portion of the visible spectrum. The device utilizes an AlInGaP die to achieve high luminous intensity and efficiency at the specified wavelength. The oval package provides a focused radiation pattern, enhancing on-axis intensity compared to a standard round LED. Electrical characteristics include a forward voltage typically between 1.8V and 2.4V at a forward current of 20mA. Reverse leakage current is typically less than 10µA at a reverse voltage of 5V. The package is constructed with a clear epoxy lens to maximize light output and provide environmental protection. Thermal resistance from junction to ambient is dependent on mounting conditions but is typically in the range of 200-300 °C/W.
