The LTL-33221AA is one of the many products from Lite-On Inc. in the LED indication – discrete category. It is a 5mm LED lamp that is compatible with wave soldering reflow soldering and manual soldering.

To begin, an LED is a semiconductor device that emits visible light when electric current passes through it. An LED light bulb includes a small chip, usually made of silicon, and two electrical contacts. The cathode, which is the negative terminal, absorbs electrons, while the anode, which is the positive terminal, emits electrons. The LTL-33221AA is no exception.

This product is compatible with the common power supply of 1.7~2.1V and a DC current of 20mA. It is durable and reliable, with a power dissipation of 40mW, a luminous intensity of 4,000mcd and an illumination angle of 120°. The package of the product is a plastic head with a 5mm lead-frame type, suitable for wave soldering and reflow soldering. The product is polarized and has a mounting angle of 60°.

The LTL-33221AA is RoHS compliant, offering a high degree of environmental assurance for electrical and electronic products. It is available in a wide range of colors, such as green, yellow, and cool white. The product is highly suitable for text and logo display, peripheral equipment, backlighting and indicator applications.

Because of its two electrical contacts, the working principle of an LED is very simple. When a voltage is applied, the electrons on the anode and the holes on the cathode are attracted each other, and then electrons on the cathode and holes on the anode move towards each other. Therefore, an electron-hole pair, which refers to a particle that includes an electron in a hole, is formed. When the electron falls into the hole, energy is released in the form of visible light.

The LTL-33221AA provides bright, long-lasting illumination for areas such as indoor and outdoor displays and signs, industrial instrumentation, automotive vehicle lighting and emergency lighting. In addition, the product is ideal for industrial applications in areas such as machine vision, automated sorting, automatic inspection, robotics and automotive painting.

Each LED component has a published life expectancy. The LTL-33221AA, for example, has a life expectancy of 40,000 to 50,000 hours when operated at room temperature and humidity. This ensures consistent high performance and flexibility during operation, while reducing downtime due to failure and maintenance.

With its high performing, safe and reliable operation, the LTL-33221AA is the ideal solution for application areas such as general illumination and indicator lights. The product is a great choice for those looking for a cost-effective and energy-efficient option for lighting.
