❓ FAQ
Q: What are the available brightness (luminous intensity) grades for the red and blue LEDs? A: The XL-A324SURUBW is available in specific bin codes. For red, codes are A5 (400-500 mcd), A6 (500-700 mcd). For blue, codes are A9 (1200-1500 mcd), B1 (1500-1800 mcd), B2 (1800-2100 mcd).
Q: How is the LED's wavelength consistency controlled? A: Wavelength is graded into specific bins. Red has codes HR04 (630-635 nm) and HR05 (635-640 nm). Blue has codes HB04 (460-465 nm) and HB05 (465-470 nm).
Q: What are the critical soldering parameters to prevent device damage? A: Reflow soldering must be at 240°C for a maximum of 6 seconds. Manual soldering is limited to 300°C for 3 seconds. The soldering point must be at least 2.0 mm from the epoxy body.
Q: Is this LED suitable for high-reliability automotive applications? A: The device has a wide operating temperature range (-20°C to +85°C) and has passed reliability tests including high-temperature storage and thermal cycling. However, specific automotive qualification (e.g., AEC-Q102) should be confirmed for your application's requirements.
Q: How does the common cathode configuration work? A: In the common cathode configuration, the cathode (negative terminal) is shared between the red and blue LED chips. The anodes (positive terminals) are separate, allowing independent control of each color by applying a forward voltage to the respective anode.
Q: What is the significance of the "frosted colloid"? A: The frosted (aerosol) colloid provides a wider, more diffused light output compared to a clear lens. This creates a softer, less glaring light, which is ideal for applications like backlighting and ambient illumination.
