Understanding the 0402 SMD LED Model

The 0402 SMD LED model refers to a specific size and type of surface-mounted light-emitting diode that is 1.0 mm long and 0.5 mm wide. This diminutive size allows for high-density circuit design, making it a favorite among engineers looking to save space on printed circuit boards (PCBs). The "0402" designation comes from the dimensions in inches, with the first two digits representing the length and the last two digits representing the width. SMD LEDs, including the 0402 model, are soldered directly onto the circuit board, which not only saves space but also enhances the device's performance by reducing inductance and capacitance. This model fits neatly into the broader category of SMD LEDs, which are renowned for their efficiency and versatility across various electronic applications.

Specifications of the 0402 SMD LED

The specifications of the 0402 SMD LED are crucial for understanding its performance and application potential. Typically, these LEDs operate at a forward voltage of around 2.0 to 3.6 volts, depending on the color and technology used. The standard current rating is about 20 mA, which allows for a brightness of approximately 1000 mcd (millicandela) for white LEDs. One of the standout features of the 0402 SMD LED is its availability in a variety of colors, including red, green, blue, and yellow, providing versatility in design. Additionally, the thermal resistance and reliability of these LEDs make them suitable for high-performance applications. Understanding these specifications helps users select the right LED for their specific needs, ensuring optimal performance and longevity.
