YONGYUTAI YLED0603R

Product FAQ

• 1. How Should I Hand-Solder or Reflow This Component onto a PCB?
  As an 0603 surface-mount device, it is best suited for automated reflow soldering using standard lead-free profiles. If hand-soldering for prototyping, use a fine-tip soldering iron set to approximately 350°C, apply heat for no more than 3 seconds per pad, and ensure the cathode mark on the LED aligns correctly with the orientation mark on your PCB layout.
• 2. What Are the Key Optical Characteristics of the YLED0603R LED?
  This discrete red LED offers a luminous intensity of 120mcd and features a wide viewing angle of 120°, ensuring excellent visibility from various directions. It is designed to operate reliably within a standard temperature range of -40°C to +85°C.
• 3. Where Is This Compact 0603 Red LED Best Applied?
  Due to its small 0603 SMD footprint and clear red illumination, this component is ideal for space-constrained indicator applications. Common deployment scenarios include status indicators on consumer electronics, network routers, power strips, wearable devices, and backlighting for small control panels or switches.
• 4. What Can I Do if the YLED0603R Is Out of Stock or if I Need a Different Color?
  If this exact part is unavailable or if your design requires a different color, you can look for any standard 0603 SMD LED package with similar forward voltage (1.8V–2.4V) and current (25mA) ratings. Popular alternatives include equivalent red 0603 components from brands like Everlight, Lite-On, or Kingbright, which share the same standard footprint.
• 5. What Are the Supported Driving Voltage and Current Limits for This Red LED?
  The YONGYUTAI YLED0603R operates with a forward voltage range of 1.8V to 2.4V and has a rated forward current of 25mA. To prevent damage and ensure longevity, you should always use an appropriate series current-limiting resistor calculated based on your specific supply voltage.
