Technical Parameters

The following table lists the main technical parameters of the H8-235 Series LEDs:

Application Recommendations

• Current Control: LEDs are current-driven components. It is recommended to use series resistors for current limiting protection to avoid damage caused by voltage fluctuations.
• Parallel Use: To ensure uniform brightness when multiple LEDs are used in parallel, it is recommended to use separate resistors for each branch.
• Ambient Temperature: High ambient temperatures can affect the performance of LEDs, so it is necessary to keep them away from heat sources.
• Storage Conditions: Unopened original packaging should be stored in an environment with a temperature of 5℃~30℃ and a humidity of less than 85%RH. After opening the package, it should be used as soon as possible, and soldering should be completed within 24 hours.

Reliability Testing

The H8-235 Series LEDs have undergone various reliability tests, including but not limited to:

• Operating Life Test: Continuous operation at rated current at room temperature for 1000 hours.
• High/Low-Temperature Storage Test: Storage at 100℃ high temperature or -40℃ low temperature for 1000 hours.
• Temperature Cycling Test: 100 cycles between 100℃ and -40℃.
• Thermal Shock Test: 100 cycles of rapid temperature change between 100℃ and -40℃.

Conclusion

With their excellent performance and wide range of applications, the H8-235 Series LEDs have become a preferred choice in the market. Whether in signal indication or decorative lighting, the H8-235 Series can provide a stable and efficient light source solution. By following the application recommendations and storage conditions mentioned above, the long-term reliability and performance of the product can be ensured.
