Quartz crystal resonator with high degree of integration

The utility model discloses a quartz crystal resonator with a high degree of integration, comprising a base, a quartz wafer, a first capacitor, a second capacitor, and a shell, wherein the quartz wafer, the first capacitor and the second capacitor are welded on the base, and the shell covers the base. The base includes a mounting seat and first to fourth welding pins arranged on the bottom surface of the mounting seat. The quartz wafer has a first electrode and a second electrode. The first electrode is electrically connected with the first welding pin and one end of the first capacitor. The second electrode is electrically connected with the third welding pin and one end of the second capacitor. The other end of the first capacitor and the other end of the second capacitor are connected to the second or fourth welding pin. The second and fourth welding pins are connected to a ground wire. The load capacitors of the resonator are integrated into the inside, so that no other load capacitor needs to be welded i
