Frequently Asked Questions
What are the key electrical and optical specifications of the XINGLIGHT XL-1608UBC-04 LED?
The XINGLIGHT XL-1608UBC-04 is a blue surface-mount LED in the industry-standard 0603 (1608 metric) package, measuring 1.6 × 0.8 × 0.4 mm. It is specified at a 20 mA forward current with a forward voltage of 2.7 V to 3.4 V. The LED has a dominant wavelength of 460 nm to 475 nm, a typical peak wavelength of 465 nm, and a 120° viewing angle, making it suitable for indicator and backlighting applications.
What should be considered when driving the XL-1608UBC-04 in a circuit?
The XL-1608UBC-04 is a current-driven LED with a maximum continuous forward current of 20 mA. To prevent excessive current caused by forward-voltage variation, a current-limiting resistor should be used in the drive circuit. The datasheet recommends using a circuit configuration that regulates the current through each LED rather than relying on constant-voltage drive alone, as forward-voltage differences can cause current imbalance and may subject some LEDs to stresses exceeding their maximum ratings. Following the recommended circuit design helps ensure reliable operation and long-term performance.
How do temperature and drive current affect the long-term performance of the XL-1608UBC-04?
Like other LEDs, the XL-1608UBC-04 performs best when operated within its specified electrical and environmental limits. Excessive drive current and elevated operating temperatures can reduce luminous intensity, affect color characteristics, and shorten service life. Following the recommended operating conditions, providing appropriate current limiting, and considering thermal management during system design help maintain stable optical performance over time.
