A question about using shell element in Abaqus

Dear All,
I am gonna model a plate(or plate-like) structure using S4R shell 
elements. The in-plane dimension of the plate is 20mm by 20mm, and 
out-of-plane dimension is 800um. For some reason, I hope to model it 
using S4R shell element with size of 50um by 50um or 100um by 100um. 
In this case, for a single shell element, its in-plane dimension 
50um or 100um is much much smaller than the out-of-plane dimension 
which is 800um. Can I mesh the plate like that? Or will any 
limitations result from this mesh? Thanks in advance.
