Hey Rams,
The SMD resistor marking “56R0” indicates this is a 56ohm resistor. We have plenty of options to choose from HERE but to properly narrow down the list to the correct results we would need to know if there are any power and tolerance ratings that need to be met, as well as the physical dimensions of the resistor to get the correct package case. These parameters can be found at the top of the search page. There is a TechForum article HERE that talks about SMD part markings.
