Working Principle

The VFHD1112H-3B72B-TR is an LED-based discrete indicator. It is a solid-state device which conjoins electronic components with a glass or plastic lens. This device is powered by a DC voltage and produces light when an electric current passes through it. When used for indication purposes, it will light up when there is power present and remain off when there is no power.

In terms of its functioning, this LED-based discrete indicator is powered by a DC voltage from an input source. The voltage source is connected to the LED via a current liming resistor. The resistor then limits the current to a safe level, thereby protecting the LED from overvoltage and excessive current. As the input is applied, current passes through the resistor, thus allowing the LED to light up.

To sum up, the VFHD1112H-3B72B-TR is a discrete LED indicator with a wide range of applications. Its features include low in-rush current, overvoltage protection and a wide operating temperature range, making it suitable for a variety of industrial and automotive applications. Its working principle is also simple and effective, with a current-limiting resistor protecting the LED from excessive current and voltage. The VFHD1112H-3B72B-TR is a reliable and robust discrete LED indicator and it is sure to meet the needs of all of its applications.
