Standard deduction

Hi,

I am having an query related to standard deduction component. I changed my organization in the middle of last year and in my new organization I provided all the CTC breakup of the previous organization. But I can see a standard deduction component in both organization's Form-16. 

I think there is a cap SD limit of 40K p.a. Could you someone correct me if I am wrong. 

or may there is a provision to claim multiple SD's if you make a switch.
