Frequently Asked Questions
Q: Is a current-limiting resistor required?
A: Yes, for 20 mA operation at 5V, use a 130Ω resistor (per Ohm’s Law: R = (5V - 2.4V)/0.02A).Q: Can it display alphabets?
A: Only limited characters (A, B, C, E, F, H, L, P) due to 7-segment constraints.Q: Is it compatible with Arduino?
A: Yes, when driven via a transistor or IC (e.g., 74HC595 shift register).Q: What’s the lifespan?
A: 50,000+ hours (typical for Vishay LEDs).Q: Is stock available?
A: Yes, contact [email protected] for real-time inventory.
