The sodium niobate-based ceramics 0.98[(Na_(1−x)/2Sm_x/2Nb_0.3TiO₃)] + 0.02MnO₂ acronymed NS_mNT of different compositions (x = 0.05, 0.1, 0.11, 0.12, and 0.13) were prepared via solid-state reaction method. The prepared samples were characterized by XRD to study the phase structure of the designed systems, SEM to study the microstructure properties of the NS_mNT ceramics. In addition to that LCR meter was used to measure the sample temperature-dependent dielectric permittivity, dielectric loss, and systems impedance. The results showed an increment in the dielectric breakdown strength (DBS) with increasing x content from 100 kVcm^–1 to 450 kVcm^–1. Similarly, the high recoverable energy density (W_rec) of 5.61 J cm^–3 was obtained for x = 0.11 symbolized (NS_mNT2) with an exquisite efficiency of 88%. The study also analyzed the complex impedance of the NS_mNT2 ceramics system to clearly understand the dielectric behavior of the system in question. A general view of things considers the NS_mNT2 ceramic system to be a reliable system for pulsed power applications.
