The main body (101) includes at least two terminals (TP, TN, TO) and a surface (102). The terminals (TP, TN, TO) are disposed on the surface (102). The two metal-wiring layers (431, 432) are disposed on the main body (101) to form two parts of metal traces connected to the two terminals (TP, TN, TO), respectively. The at least one metal block (421, 422, 423) is embedded within the main body (101) and connected to one of the two terminals (TP, TN, TO). A thickness of the two parts of metal traces is less than that of the metal block (421 422, 423). The two terminals (TP, TN, TO) connected by the two parts of metal traces have a loop inductance less than or equal to 1.4 nH calculated at a frequency greater than 1 MHz.
