The A203B/G is a standard LED manufactured by Everlight Electronics Co., Ltd. It's a through-hole LED, commonly used for indication purposes across a wide array of electronic devices. While specific detailed specifications are difficult to ascertain due to the wide range of possible product variations, it is known for its reliability and ease of integration.

Applications:

• Indicator lights on consumer electronics (e.g., TVs, DVD players, appliances).
• Panel indicators in industrial equipment.
• Status indicators on computer peripherals (e.g., printers, modems).
• Backlighting for small displays.
• General purpose LED indication in various electronic circuits.

Features:

• Standard through-hole package for easy mounting.
• Diffused lens for wide viewing angle.
• Low current operation.
• High luminous intensity.
• Long lifespan.

Benefits:

• Provides clear visual indication.
• Easy to integrate into existing circuits.
• Energy efficient operation.
• Durable and reliable performance.
• Cost-effective solution for indication needs.

Additional Details:

The A203B/G typically operates at a forward voltage of around 2.0-2.4V and a forward current of 20mA. The luminous intensity and color (typically green, given the '/G' suffix) vary depending on the specific bin. The viewing angle is generally wide, around 60-70 degrees. The package is a standard 5mm through-hole type. It's commonly used due to its simplicity and availability.

When using the A203B/G, it is important to use a current-limiting resistor in series with the LED to prevent damage from overcurrent. The value of the resistor should be calculated based on the supply voltage and the forward voltage of the LED.
