The invention relates to an electronic element array and printed circuit board thereof, the electronic element array comprises at least two different electronic elements arranged in the same encapsulation, each electronic element is respectively leaded out an input terminal and an output terminal. The invention improves a resistance array of the same resistance value in a multi-channel into a resistance array of various resistance values in a multi-channel, improves a capacitance array of the same capacitance value in a multi-channel into a capacitance array of various capacitance values in a multi-channel, improves the resistance array and the capacitance array into a resistance and capacitance array mixing with the resistance and the capacitance, the invention is used for the place with small layout space for adjusting performances of the resistance array of different resistance values, the capacitance array and the capacitance arrays of different capacitance values on the signal line, the invention can provide more values combination for selecting because of adopting electronic elements of different values.
Description
technical field [0001] The present invention relates to the field of circuits, in particular to the technology of resistance exclusion and capacitance displacement. Background technique [0002] At present, as the size of electronic products continues to shrink, the size restrictions on printed circuit boards (PCB: Printed Circuit Board) are becoming increasingly strict. In order to reduce the number of components and improve the integration of components, resistance exclusion and capacitance displacement are widely used in existing technologies. , to replace multiple discrete resistors and capacitors, so that the PCB board layout space is more abundant. [0003] In the prior art, the resistors are packaged by several resistors with the same parameters. In some resistors, the pins on one side of multiple resistors are connected together as common pins, and the pins on the other side are connected together. lead out respectively. Resistors are generally used in digital circ...
