What is the maximum voltage across this resistor at its rated power?
At 0.25 W, the voltage across a 3.9 Ω resistor is about 0.99 V (V = √(P × R)). Connecting 5 V directly across it would draw about 1.3 A and far exceed its rating, so it suits only low-voltage, low-current circuits.
Can I use it to limit the current through an LED from a 5 V supply?
No. With a typical red LED (about 2 V forward voltage) on a 5 V supply, this value would let about 0.8 A flow, which is far too much. For LED current limiting, use a much higher value such as 330 Ω to 470 Ω.
