The electrical and resonance characteristics of energy-trapped 20 MHz SMD-type resonators using the 3rd overtone thickness vibration mode were investigated as a function of internal electrode diameter. With increasing electrode diameter, resonant resistance in the 3rd overtone mode decreased and electromechanical coupling factor ($k_{\text{t3}}$) in the 3rd overtone mode showed constant values. Taking into consideration the mechanical quality factor ($Q_{\text{mt3}}$) of 5,552 and dynamic range (D.R.) of 60.72 dB in the 3rd overtone mode, the ceramic resonator with the electrode diameter of 1.13 mm was found to be suitable for 20 MHz resonator application.
