Product FAQ

  • 1. How Should I Calculate the Current-Limiting Resistor Value Before Implementation?
    To safely implement this LED, you must place a resistor in series to limit the current. Use Ohm's law: subtract the LED forward voltage (typically 3.0V) from your supply voltage, and divide that number by your target operating current (e.g., 20mA or 0.02A) to find the required resistance in ohms.
  • 2. What Are the Key Technical Specifications Regarding Power and Brightness?
    The YLED0603B operates at a forward current of 30mA with a forward voltage range of 2.6V to 3.2V. It delivers a luminous intensity between 42mcd and 86mcd, emitting a blue light with a dominant wavelength of 460nm to 475nm and a wide viewing angle of 120°.
  • 3. What Are the Ideal Application Scenarios for This Component?
    This discrete blue LED is ideal for low-power indication purposes. Common application scenarios include status indicators on consumer electronics, network routers, smart home devices, handheld instruments, and backlighting for small control panels or switches.
  • 4. What Are the Best Alternatives From Other Brands if This Component Is Out of Stock?
    If the YONGYUTAI YLED0603B is unavailable, you can look for any standard 0603 blue indicator LED with a forward voltage of 2.6V–3.2V, a dominant wavelength around 460nm–475nm, and a 120° viewing angle. Major brands like Everlight, Lite-On, or Kingbright offer drop-in replacements with identical footprints.
  • 5. Is This Blue LED Compatible With Standard Reflow Soldering Processes?
    Yes, this SMD LED is designed for automated assembly. It features standard 0603 packaging and an operating temperature range of -40°C to +85°C, making it fully compatible with standard surface-mount technology (SMT) reflow soldering profiles.
