The NTC Series Negative Temperature Coefficient Resistors are designed for applications requiring precise temperature sensing and control. They exhibit a decrease in resistance with an increase in temperature.
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 90 slowly 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)
Rated Zero-Power Resistance RN (): RN20%
Testing Voltage: 1.5VDC
Test Conditions: Ambient temp. Range: 25C2C (TA). After placing for 1~2 hours under TA, the resistance value shall be measured.
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.
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.
B=T1*T2/(T2-T1) x Ln(R1/R2)
R1, R2 is zero-power resistance at T1, T2
T1=298.15K (25C) T2 = 323.15 K (50C)
See the main technical parameter list.
No visible mechanical damage. RN /RN 20% (RN = | RN-RN' | ). Ta:-403C/ 30min252C/ 5minTb:2003C/30min252C/ 5min Cycles: 5 times. After recovering 4~5 h under 252C, the rated zero power resistance value RN shall be measured.
