Frequently asked questions
Can this resistor handle 1 A?
No. P = I²R, so 1 A through 1.8 Ω dissipates 1.8 W, about seven times the 1/4 W rating. The maximum current at 1/4 W is about 0.37 A (I = √(P/R)).
Is this resistor suitable for precise measurement or current sensing?
The listing does not give tolerance or composition, so it is not specified for precision work. For current sensing, check the tolerance and power rating in the datasheet and make sure the power rating is sufficient for your current.
