5HD12V LED Indication - Discrete

The 5HD12V is one of the most versatile LED indication products available on the market today. Its small size and high efficiency make it an ideal choice for a variety of applications. This article will explain the application field of 5HD12V and its working principle.

Application Field

The 5HD12V is a cost-effective solution for a wide range of needs, especially when light output and energy efficiency are of paramount importance. It can be used to provide an indication of any low voltage system, from small circuits to high-voltagecircuits and systems. Due to its high power efficiency, the 5HD12V is especially well-suited for applications such as:

• Automotive and marine housings
• Electrical panel displays
• Low voltage illuminated safety signs
• Industrial equipment status indicators
• Display cases
• Decorative lighting
• Backlit LCD and OLED screens
• Vehicle control signals
• Emergency exit signs

Working Principle

The 5HD12V is a low voltage LED indication product that uses a PTC (positive temperature coefficient) resistor to maintain a constant current output through the LED. The PTC resistor is made of a semiconducting material that has a negative temperature coefficient; when the LED gets too hot it will increase the resistance and decrease the current, maintaining the LED’s brightness.The 5HD12V is designed to work with 9 to 16VDC (AC or DC) input voltage. It has an open circuit voltage of 2.5V and a current rating of 20 mA. The 5HD12V has a built-in heat sink to dissipate heat, which keeps it cool and running efficiently.The 5HD12V is designed to be used in connection with a 3-pin or 2-pin LED configuration; with the 2-pin LED, the 5HD12V directly powers the LED, while with the 3-pin LED, one pin of the LED is connected to the input voltage and the other two are connected to the 5HD12V.

Conclusion

The 5HD12V is an efficient and reliable LED indication solution that provides a wide range of options for low voltage systems. Due to its small size, high efficiency, and cost effectiveness, the 5HD12V is an ideal choice for a variety of applications. Through the use of its PTC resistor, the 5HD12V maintains a constant current output and can be used with either a 3-pin or 2-pin LED configuration.
