3A-01-B71-Y9C-A1R2T1EH

LED indicators are one of the most commonly used indicator lights, and no matter which color, type, and area size, they all have one commonality: 3A-01-B71-Y9C-A1R2T1EH. This technology, comprised of two parts, the anode and cathode, has empowered LED indicators to maintain their status as one of the most widely used methods for indication in laboratories, industrial controls, and consumer electronics.

LED indicators using the 3A-01-B71-Y9C-A1R2T1EH technology are categorized as discrete LED indicators, meaning that when activated, a single LED illuminates without involving other LEDs in its vicinity. This is in contrast to LED display indicators, which often require multiple LEDs to create shapes and characters. As an added benefit, discrete LEDs require fewer connections and therefore, less wiring, making them a great solution when in limited space.

The most common way to classify LED indication with 3A-01-B71-Y9C-A1R2T1EH technology is by the current level that is required to activate it. The classification is based on the current level and color of the emitted light (red, green or yellow). Low-level LEDs only need a small amount of current to trigger, around 10mA or less. These are commonly used in consumer applications such as warning systems, and can be attached directly to a microcontroller without any additional components. Medium and high-level LEDs require more wattage, from 20mA to a few hundred mA, so they are used in less constrained applications including medical and automotive applications.

In terms of working principles, all LEDs have an anode and cathode, so the principle is usually a simple on/off switch with one controlling the current and the other being grounded. Smaller LEDs, like the ones used in discrete applications, can be controlled directly. On the other hand, high power or mid-level LEDs, require resistors to ensure that the current does not exceed a predetermined quantity, which can damage the LED.

User interfaces for LED indications vary depending on the application, for smartphones, for example, OLEDs are the most common, using a reverse current polarity. If the cathode is connected to the positive/higher voltage, current will flow through the LED and the LED will be switched on. Conversely, when the voltage is reversed, current cannot flow and the LED is switched off. However, for mid/high-level LED indicators, separate current control switches are installed to control the amount of current flow and thus the brightness of the LED.

In conclusion, LED indication through the 3A-01-B71-Y9C-A1R2T1EH technology, is an effective way to produce discrete indicators for various applications, depending on the voltage requirement of the LED. Low-level indicators are commonly used in consumer applications while mid/high-level indicators are used in more demanding applications such as automotive, medical and engineering. Users can also control the LED interface according to their needs, controlling either the current flow or the reverse current polarity (as needed). All in all, the 3A-01-B71-Y9C-A1R2T1EH technology is a reliable and versatile way to power discrete LED indicators.
