Resistancetemperaturecoefficient (RTC) of step function PTC thermistor depends on it's measurement methods, therefor the obtained results are not unique and comparable.
目前突变型PTC元件电阻温度系数的测量方法各种各样，因此测试结果缺乏唯一性和可比性。

However, to be useful, they must be characterized for capacitance value, voltage rating, temperaturecoefficient, and leakage resistance.
然而，要使用电容器就必须明白其特性：包括电容值、额定电压值、温度系数以及泄漏电阻等。
