Abstract.  In this work, we first discuss the existence of a mild solution of the Caputo fractional non-instantaneous impulsive integro-differential equation and then discuss its stability in the sense of Ulam-Hyers. We establish our main results by using the well-known Banach fixed point theorem. Two suitable examples are presented to authenticate the results. In addition, with the help of the obtained results, the bound for a non-instantaneous impulsive fractional-order RLC circuit current is estimated, and it is found that the bound primarily depends upon the bandwidth and the fractional order of the RLC system. Further, for a given bandwidth, we show how the fractional order of the system influences the behavior and magnitude of the current.
