HDSP-7807 is a seven segment numeric display module from Harwin. This module is specially designed for a wide range of applications, such as consumer products and industrial processes. Its main features include industrial-grade reliability, strong corrosion resistance, and a long life span.

The HDSP-7807 module is based on light emitting diode (LED) displays and provides a 7-segment (*ABCDEFG) display for numerical information. Its internal characteristic makes it suitable for use in various applications, such as industrial process displays, kiosks, communications systems and automotive applications.

The HDSP-7807 comes in an 8-pin, 2 row, mini-DIP format and uses a common anode design. The HDSP-7807 has a narrow viewing angle and operates in two directions, such as viewed from the top and viewed from the bottom. It is designed to be used with commonly available discrete NPN drivers and constant current sources, with a nominal input voltage of 5 VDC.

In terms of its technical specifications, the HDSP-7807 has a wide operating temperature range of -40°C to 85°C, making it suitable for a wide range of applications. It has a total current rating of 15 mA, with a peak current rating of 20 mA.

The HDSP-7807 also features a ruggedized build, allowing it to be used in challenging industrial and automotive applications. It has an extended automotive lifetime of up to 500,000 operations, and a high level of contact resistance. It is also designed to be very reliable in harsh environments, such as shock, vibration and humidity.

The working principle of the HDSP-7807 is based on a continuous current flowing through the circuit. As the current passes through the LEDs, light is produced, which then creates numerical information on the display module. The LEDs are connected in series, so that the current flows from one LED to the next, allowing for a series of uniform digits to be formed.

In summary, the HDSP-7807 seven segment numeric display module from Harwin is a reliable and ruggedized module suitable for use in a wide range of applications. Its wide operating temperature range, extended lifetime and strong corrosion resistance make it well suited for industrial, automotive and other harsh environments. Its working principle is based on an LED light emitting process and continuous current passing through the circuit.
