Negative Temperature Coefficient Resistor NTC Series

The NTC Series resistors are designed for applications requiring temperature-dependent resistance. They exhibit a negative temperature coefficient, meaning their resistance decreases as temperature increases. These components are crucial for overcurrent protection, inrush current limiting, and temperature sensing.

Electrical Characteristics

Item	Specification	Test Conditions & Methods
Rated Zero-Power Resistance RN ()	RN20%	Ambient temp. Range:25C2C(TA). Testing voltage: 1.5VDC. After placing for 1~2 hours under TA, the resistance value shall be measured.
Thermal Dissipation Constant (mW/C)	See the main technical parameter list	The thermal dissipation constant() could be calculated by the ratio of a change in power dissipation(P) of the thermistor to a change in temperature(T) of the thermistor at a specified ambient temperature.
Thermal Time Constant T(s)	See the main technical parameter list	The time(t) shall be measured within which the temperature is reached at 63.2% of the ambient temperature change under zero power condition change of NTC thermistor.

Reliability Test

Item	Specification	Test Conditions & Methods
Strength of lead terminal	No break out AR/RN <20% (AR = \|RN-RN'\|)	Fasten the body and apply a force gradually to each lead until 10N and then keep for 10sec. Hold body and apply a force to each lead until 90slowly at 5N in the direction of lead axis and then keep for 10sec, and do this in the opposite direction repeat for other terminal. After recovering 4~5h under 252C, the rated zero power resistance value RN' shall be measured. (See IEC68-2-21/GB2423.29 Ua / Ub)
