Model and Color

The following is a table comparing the color and main technical parameters of the H19-328 series LED lights:

Application Guidelines

Circuit Design：To ensure stable operation of the LED, it is recommended to use current-limiting resistors and design independent circuit paths for paralleled LEDs.

Storage and Handling：LEDs should be stored in an environment with a temperature between 5°C and 30°C and a relative humidity of no more than 85%. If more than 168 hours have passed after opening, dehumidification treatment should be performed.

Soldering Guidelines：Soldering conditions should be strictly adhered to, avoiding exceeding the maximum soldering temperature and time limits. After soldering, mechanical force on the LED or bending of the PCB should be avoided.

ESD Protection：LEDs are sensitive to static electricity, so appropriate anti-static measures should be taken during operation, including wearing anti-static wristbands, using anti-static packaging, and ensuring equipment grounding.

Cleaning and Maintenance：It is recommended to use alcohol-based solutions such as isopropyl alcohol to clean LEDs, avoiding corrosive solutions.

Reliability Testing：The H19-328 series of LED lights has undergone a series of rigorous reliability tests, including endurance testing, high-temperature and high-humidity storage testing, temperature cycling testing, thermal shock testing, and reflow soldering testing, to ensure product reliability and durability.

Conclusion：The QILSTE H19-328 series of LEDs are an ideal choice for a variety of electronic devices due to their superior performance and reliability. By following detailed application guidelines and maintenance advice, the lifespan and performance of these LEDs can be maximized.

The appearance and specifications of the product may be modified for improvement without prior notice. For special applications, such as in medical equipment and safety devices, it is recommended to consult the QILSTE sales department to ensure product suitability. Attention should also be paid to the fact that high-brightness LED products may cause eye injury when lit, and direct viewing should be avoided.
