Frequently Asked Questions
What forward current and voltage does the KP-3216QBC-D require for a typical blue LED indicator circuit?
The KP-3216QBC-D operates at a maximum forward current of 30 mA and up to 4 V forward voltage. A typical indicator circuit uses 10 mA to 20 mA with a current-limiting resistor calculated from the supply voltage minus 3.2 V (typical Vf) divided by the desired current, achieving 40 mcd to 80 mcd luminous intensity.
How does the KP-3216QBC-D's luminous intensity compare to standard 5 mm blue through-hole LEDs for panel indicators?
The KP-3216QBC-D achieves 100 mcd typical luminous intensity in a 3.2 × 1.6 mm SMD package, comparable to many 5 mm through-hole blue LEDs rated at 80 mcd to 200 mcd. Its SMD format reduces mounting height to 1.10 mm versus the 8 mm to 12 mm of 5 mm LEDs, enabling flatter product designs without sacrificing visible brightness.
Can the KP-3216QBC-D be driven directly from a 3.3 V MCU GPIO pin with a current-limiting resistor?
Yes — with a 3.3 V GPIO supply and a typical forward voltage of 3.2 V, a 10 Ω to 33 Ω series resistor limits current to a safe 3 mA to 10 mA range. At 10 mA the KP-3216QBC-D still produces approximately 30 mcd to 40 mcd, sufficient for visible blue status indication on development boards and embedded systems.
