| Abstract: | The PTC component being presented in this article is a special kind of positivetemperature coefficient resistance component, which feature of value of resistance -temperature can be characterized by "delayed action of switching off". If the PTCcomponents substitute the timer to be used in some electric bang-bang control circuits, thecircuits can be simplified and their reliability can be raised. This article presents twoexamples of the PTC component and discusses some practical problems. |
