In this study, a simple AT-cut crystal resonator and an oscillator utilizing a Bi0.5(Na0.84K0.16)0.5TiO3 relaxator ceramic as a load capacitor were designed and their frequency–temperature characteristics were investigated. To modify the temperature dependence of the dielectric constant, Bi0.5(Na0.84K0.16)0.5TiO3 ceramics were manufactured with variations in the level of Sr substitution. At a composition with 6 mol % Sr substitution as a load capacitor, the frequency–temperature characteristics of the AT-cut crystal resonator and oscillator with a series load capacitance were varied similarly to those of cut orientation variation, and also compensated.
