25℃零功率电阻值 Nominal Zero-Power Resistance at 25℃(R25) |
在施加最大工作电压 3 分钟并在 25°C 温度下搁置 2 小时后,施加小于DC1.5V 的电压(小于 10mA 的直流电流)来进行测量。 After applying maximum operating voltage for3min.leaving for 2hrs.in25°C,measured by applying voltage less than DC1.5V. (by a direct current less than 10mA) |

居里温度 Curie temperature (℃) |
PTC热敏电阻在达到某一温度前, 电阻值是恒定的,一旦超过这一温度, 电阻值也会急剧上升。这一电阻值的变化点成为“居里点 (也称为居里温度) ”,即25℃时电阻值的2 倍电阻值所处的温度。 The resistance of the PTC Thermistor remains almost constant up to a certaintemperature,theresistancesuddenlyincreasesafteracertaintemperature.Thechanging point ofthis resistance is called the"Curie point (Curie temperature) ", wedefinethispointasthetemperaturewheretheresistancebecomesdoubleofthe resistance at 25°C. |
