Abstract

The invention relates to the technical field of a component structure and particularly relates to a LRC component structure. The LRC component structure comprises the steps that: two metal support electrode plates are arranged on the element end electrode for electric connecting and fixing and buffering roles; two electrode plate supports are provided with a derivation pin derived inward or outward in the bottom; the derivation pin is fixedly connected to a circuit board; multichip LRC elements which are in series connection or parallel connection are soldered inside the two electrode plate supports. The multichip resistance capacitance element is vertical stack installation or horizontal stack installation. According to the corresponding principle or function of circuit, corresponding pins are only soldered on a bonding pad at using time, the LRC element bodies not touch the bonding pad, the impacts made by undesirable stress such as mechanical stress, temperature stress and the like are reduced by the buffer function of the electrode plate supports, the reliability for the LRC components is increased. The elements installation occupancy area is effectively saved through the stack component modular structure, and the line distribution parameter is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of component structures, in particular to an LRC component structure. Background technique [0002] Chip RC sensor is a common passive component, which has the characteristics of small size, good resistance to heat and humidity, and high cost performance. At present, it has been widely used in computers, various electronic equipment, aerospace and other fields, and has become an indispensable part of electronic equipment. In electronic circuits, capacitors, resistors, and inductors (LRC) are used in series and parallel. According to different combinations, they can be designed into products such as low-pass filters and high-pass filters or realize functions such as resonant circuits and LRC networks. . [0003] Usually when we use SMD LRC components in practice, we first design PCB, ceramic substrate and other circuit boards according to the circuit schematic diagram, then solder the resistance-capacitance...
