| Abstract: | Abstract The effects of temperature coefficient and microstructure on over-current withstanding characteristic of PTC over-current protector were studied. Experimental results indicate that the electronic characteristic can be increased with the raise of temperature coefficient by changing sintering procedure. The correlation between over-current withstanding a-bility and microstructure has been investigated. |
