Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a high temperature resistant chip capacitor. Background Art

[0002] High temperature resistant chip capacitors, also known as SMD capacitors, are indispensable electronic components in the manufacture of modern electronic equipment. The material of high temperature resistant chip capacitors is X8L, and the maximum temperature resistance can reach 150°C. High temperature resistant chip capacitors are electronic components manufactured using surface mount technology. They are directly fixed on the circuit board by welding. Compared with traditional plug-in capacitors, chip capacitors have the advantages of small size, light weight, and high reliability. In the field of industrial control, chip capacitors are also widely used. For example, chip capacitors are needed in programmable logic controllers (PLCs), sensors, actuators and other equipment. In these applications, the stability and temperature resistance of chip capacitors are key factors.

The ceramic chip capacitor, through the arrangement of the protective shell, the capacitor body, the copper heat pipe and the aluminum heat sink fins, when in specific use, the capacitor body will generate a large amount of heat when it is working, and the heat generated will be first absorbed by the protective shell, and the protective shell will then transfer the heat to the copper heat pipe. The arrangement of the copper heat pipe allows it to absorb the heat of the capacitor body absorbed by the protective shell, and then transfer the heat to the aluminum heat sink fins. The heat sink fins are made of aluminum, which can help the heat dissipate quickly and improve the heat dissipation effect of the ceramic chip capacitor."

[0004] However, the ceramic chip capacitor in the above-mentioned public document mainly considers improving the heat dissipation effect of the ceramic chip capacitor, which is not convenient for protecting the capacitor and avoiding external electromagnetic interference to the normal operation of the capacitor. When the capacitor body is working, its own performance in blocking external electromagnetics is low, which may cause the capacitor body to be affected by nearby electromagnetic interference and affect its work.

[0005] In view of this, it is necessary to develop an anti-electromagnetic interference mechanism to protect the capacitor and prevent external electromagnetic interference from affecting the normal operation of the capacitor. Utility Model Content
