| Abstract: | ELECTRONIC COMPONENTS & MATERIALS (China), Vol 18, No 6, P 7 8 (Dec 1999) In Chinese The effect of hot aging on the value of resistance of polymer PTC, and the effect of electric aging on its electric properties, such as the over current withstanding characteristic, voltage withstanding characteristic, thunder withstanding characteristic are investigated. The results show that change of hot aging conditions would cause change of polymer PTC resistance; electric aging can improve its electric properties effectively. (5 refs.) |
