Green 568nm LED Indication - Discrete 2.2V Radial The WP483GDT is a through-hole green light-emitting diode designed for general-purpose visual indication and low-power lighting applications. It emits a visible green wavelength when forward biased and is commonly used in status indicators, signal displays, and basic illumination circuits. The device is built with a durable epoxy lens package that provides mechanical protection and enhances light output visibility. It is suitable for use in a wide range of electronic systems, including consumer electronics, control panels, and embedded designs. Device Overview The component is a standard discrete LED with a two-lead configuration consisting of an anode and a cathode. It operates by converting electrical energy into light through electroluminescence. The emitted color falls within the green spectrum, making it appropriate for applications requiring clear visual signaling without excessive brightness or power consumption. Electrical Characteristics The LED operates under forward bias conditions, with a typical forward voltage in the range expected for green LEDs. It supports low current operation while maintaining consistent luminous output. Reverse voltage tolerance is limited, and proper polarity must be observed to prevent damage. Current-limiting resistors are required in circuit integration to ensure safe operation. Optical Characteristics The device produces a green light output with a defined luminous intensity and viewing angle based on its lens shape and internal structure. The epoxy lens may be diffused or clear, affecting the spread and focus of the emitted light. Brightness is dependent on the forward current applied. Mechanical Characteristics The LED is housed in a standard round through-hole package, compatible with typical PCB mounting. Leads are spaced to fit common board layouts and can be soldered directly. The epoxy body provides insulation and environmental protection while maintaining optical clarity. Thermal Considerations The device is designed for low power dissipation but should be operated within recommended limits to avoid overheating. Adequate spacing and proper current control help maintain thermal stability and prolong device lifespan. Applications The WP483GDT is suitable for indicator lights in electronic devices, status displays in control systems, educational and hobby electronics, and general-purpose signaling applications where green illumination is required. Compliance and Handling The component should be handled using standard ESD precautions. Storage and soldering conditions should follow typical LED handling practices to maintain performance and reliability. #commonpartslibrary #led #green
