| Abstract: | Using tap-casting-lamination forming, four layers end-electrode structure, soak plating protection agent and through sinter curve for control of R25 and α, the 0603 type chip PTC thermistor were prepared. This ceramic was used for over-heat protection. Technical indexes of obtained products are as follows: measuring temperature points: (85±5) ℃ and (105±5) ℃; temperature coefficient α: >10% ℃–1 and jump range: >104. |
