Abstract

The invention relates to a passive element with high surge and current withstanding characteristic. A metal sheet is arranged in the current loop of the passive element, to cause the current to pass through the metal sheet to be evenly dispersed, the passive element is generally provided with a silver electrode arranged on a ceramic chip, the silver electrode is led out from two terminals, through the arrangement of the metal sheet, the contact area of the terminals and the silver electrode can be increased, and the uniformity degree of the surge current passing through the silver electrode is improved, to cause no ablation phenomenon of a silver layer to be produced, to ensure that the operation of the invention is stable. The invention also discloses a method for improving the withstanding characteristic of the passive element to the surge current.

Description

technical field [0001] The invention relates to a passive component with high surge current tolerance, in particular to a lightning protection varistor, a varistor with thermal protection function, a surge current suppressing NTC thermistor, and in application Other components that absorb surge currents by body effect. . Background technique [0002] Among the passive components in the prior art, for example, resistors can be divided into two types with thermal protection function and without thermal protection function, as shown in Figure 5 to Figure 8 are resistors with thermal protection function in the prior art, as shown in Figure 9 and Figure 9 10 shows a resistor without thermal protection in the prior art. [0003] The prior art surge current suppression type NTC thermistor has the same structure as that of FIGS. 9 and 10 described above. [0004] Please refer to Figs. 5 to 8, the first embodiment of the prior art has a ceramic sheet 70, a silver electrode 71, a f...
