Stackable capacitor and capacitor stacking structure with stackable capacitor

Abstract

The invention provides a stackable capacitor, comprising a body, a first pedestal and a second pedestal. The body comprises a first end face and a second end face opposite to the first end face, wherein the first end face extends vertically to form two first pins, the second end face extends vertically to form two second pins, and each first pin is electrically connected to a corresponding second pin. The first pedestal comprises a first pedestal body and two first bonding pads fixed on the first pedestal body, wherein the first pedestal body is arranged on the first end face of the body, and each first bonding pad is connected with a corresponding first pin. The second pedestal comprises a second pedestal body and two second bonding pads fixed on the second pedestal body, wherein the second pedestal body is arranged on the second end face of the body, and each second bonding pad is connected with a corresponding second pin. The second pedestal which is electrically connected with the first pedestal is arranged on the second end face of the body, so that another capacitor can be connected to the second pedestal in a stacking way. The invention also provides a capacitor stacking structure.

Description

technical field [0001] The invention relates to a capacitor structure, in particular to a stackable capacitor and a capacitor stack structure using the stackable capacitor. Background technique [0002] Capacitor is one of the essential components in the circuit, which is often used to filter out noise in the circuit. Most traditional chip capacitors include a body and a gasket electrically connected to one end of the body, and the capacitor is attached to a circuit board through the gasket. [0003] In the process of circuit development, it is often difficult to determine the number and parameters of capacitors in the circuit. The specific structure of traditional capacitors causes the following problems in the design: (1) When wiring, it is necessary to reserve a position for placing capacitors on the circuit board. The remaining position may be insufficient or too much, resulting in unreasonable wiring; (2) When replacing the capacitor with another larger capacitor in th...

[0003] In the process of circuit development, it is often difficult to determine the number and parameters of capacitors in the circuit. The specific structure of traditional capacitors causes the following problems in the design: (1) When wiring, it is necessary to reserve a position for placing capacitors on the circuit board. The remaining position may be insufficient or too much, resulting in unreasonable wiring; (2) When replacing the capacitor with another larger capacitor in the original position of a certain capacitor, due to the gap between adjacent components The space is too small to accommodate the large capacitor, so that the circuit cannot meet the electrical characteristics specified by the customer
