Introduction to SMD LED 0805

SMD LED 0805, also known as a surface mount LED, is a type of light-emitting diode that is designed for surface mounting on a printed circuit board (PCB). The "0805" refers to the size of the LED, which measures 8.0mm x 5.0mm. This small size makes it highly suitable for various applications where space is limited and a high brightness output is required.

Design and Construction

The SMD LED 0805 is constructed using a phosphor coating that converts the electrical energy into visible light. The phosphor is applied to a small die that is mounted on a lead frame. The lead frame serves as the electrical connection between the LED and the PCB. The design of the SMD LED 0805 allows for efficient heat dissipation, which is crucial for maintaining the longevity and performance of the LED.
