    Hi,

    I am looking for a 470r 1/2w 5% resistor. I have found the good product but with a tolerance of 1%.

    I have to admit my ignorance. What is the impact of the tolerance and is a 1% tolerance suitable for my need ?

    Thanks in advance for your help

    1% is fine. The less tolerance, is usually more expensive. It means it is 470 Ohms plus or minus 1%. Way more accurate than plus or minus 5%.

    Usually you see 5%, 10%, even 15%. Depending on circuit if it matters or not.

    The 1% tolerance is perfectly fine.

    Thank you pals, quick ansers, I am about to order.

    This resistor is for the pcb driving the propellor of the whirlwind topper. Input vac is there but not as output. The resistor r2 has gone

    Thanks a lot

    Quoted from jimy_speedt:

    The resistor r2 has gone
    Thanks a lot

    That means it is now a fuse

    Yes not sure the other components are still ok, so I will change them. Hopefully the ic has no injury, I ll replace at the very end
