4040 LED, also known as a 4040 SMD LED, is a popular type of surface-mounted device (SMD) that has found widespread application in various industries. These LEDs are characterized by their compact size, high efficiency, and excellent heat dissipation capabilities, making them ideal for use in a multitude of lighting applications.

Introduction to 4040 LED Technology

The 4040 LED is a member of the 4mm x 4mm SMD LED family, which includes other popular sizes like the 3528, 5050, and 5630. The "4040" designation refers to the physical dimensions of the LED, with "40" representing the length and "40" the width in millimeters. These LEDs are typically mounted on a PCB (printed circuit board) using a leadless process, which contributes to their compact form factor.

Key Features of 4040 LEDs

One of the primary features of the 4040 LED is its small size, which allows for high-density mounting on PCBs. This compact design is particularly beneficial in applications where space is limited, such as in LED strips, panels, and displays.
