The main parameters of the power thermistor NTC.Microwave Sensor Module Radar Sensor

　　1. Rated zero-power resistance (R25): also called the nominal resistance value, unless otherwise specified, refers to the resistance value of the power NTC thermistor measured at an ambient temperature of 25°C. Commonly used resistance values are 2.5Ω, 5Ω, 10Ω, etc. The commonly used resistance errors are: ±15%, ±20%, ±30%, etc.

　　2. Maximum steady-state current (A): The maximum current that can be continuously applied to the power NTC thermistor at the nominal ambient temperature.

　　3. Maximum allowable capacitance (joule energy) (UF): the maximum allowable capacitance value of a capacitor connected to a power NTC thermistor under load.

　　4. Operating temperature range (℃): The ambient temperature range that the power NTC thermistor can work continuously under zero power state, which is determined by the upper limit category temperature and the lower limit category temperature.
