Electro-Optical Characteristics

• Forward Current: A forward current of 10 mA, complemented by a 20 mA pulse forward current, ensures the brightness and response speed of the LED beads.
• Reverse Voltage: A reverse voltage limit of 5V ensures the safety of the product.
• Operating and Storage Temperature: Stable performance is maintained within an operating temperature range of -30°C to +85°C and a storage temperature range of -40°C to +100°C.
• Power Dissipation: With a power consumption of 25 mW for red, and 36 mW each for green and blue, the product achieves a perfect combination of high brightness and low power consumption.

Reliability Testing The product has undergone a series of rigorous tests, including thermal shock, humidity and temperature cycling, high and low-temperature storage, and resistance to soldering heat, demonstrating exceptional reliability and durability.

Soldering and Cleaning Guidelines

• Hand Soldering: It is recommended to use an iron with a power of less than 20W, maintaining a temperature below 360°C, with each soldering lasting no more than 3 seconds.
• Reflow Soldering: Follow the Pb-Free reflow soldering temperature profile, and do not perform more than two cycles, avoiding exerting any pressure on the LED during the ramp-up process of soldering.
• Cleaning: Alcohol cleaning is recommended, with attention to temperature and time control to avoid solvents that may damage the LED encapsulation.

Storage and Static Protection

• Moisture-Proof Packaging: The product is packaged in a sealed moisture-proof and anti-static bag, complete with desiccants and a humidity card to ensure the safety of the product during transportation and storage.
• Baking for Moisture Removal: Products before and after opening should be baked according to the specified process to maintain optimal performance.

Design Recommendations When designing the circuit, the current through each LED must not exceed the maximum rating, and protective resistors must be used to prevent unnecessary changes in current. Additionally, thermal design is crucial for maintaining the performance of the LEDs.

Precautions for Use

• Reverse Voltage Protection: It is suggested that the reverse voltage applied to the LED does not exceed 5V to prevent damage and performance degradation.
• Temperature Protection: In high-density array applications, it is recommended to keep the surface temperature below 55°C and the leg temperature below 75°C.
• Handling Products: Avoid touching with bare hands to prevent contamination and static damage. Excessive force should be avoided, especially when the product is at high temperatures, such as during reflow soldering.
