Science and technology bring about changes in productivity. With the support of technology, each industry continuously innovates and changes to adapt to the needs of the market. Resistors are used in many fields. The glass encapsulated NTC thermistor meets the requirements of temperature detection in many fields, improves people's work efficiency, and keeps the temperature within a safe range.
What are the technical terms of the glass encapsulated NTC thermistor?
What is a glass encapsulated NTC thermistor?
What is the performance of the glass encapsulated NTC thermistor?
Zero power resistance RT (Ω)
RT is the measurement power that allows negligible change in resistance value compared to the overall measurement error, and refers to the resistance value measured at a specific temperature T.The relationship between resistance value and temperature change is:
RT = RN expo(1/T – 1/TN)
T: Specified temperature (K).
This relational expression is an empirical expression that has a certain accuracy only within the limited range of the rated temperature TN or the rated resistance value RN.
Rated zero-power resistance value R25 (Ω)
According to national standards, the nominal zero power resistance is the resistance R25 measured with an glass encapsulated NTC thermistor.
This resistance value is the nominal resistance of the glass encapsulated NTC thermistor.In general, the resistance value of the glass encapsulated NTC thermistor is also related to this value.
Material constant (thermal index) B value (K)
T1, T2: Two specified temperatures (K).
For frequently used glass encapsulated NTC thermistors, the B value range is generally between 2000 K and 6000 K.
Zero power resistance temperature coefficient (αT)
At a given temperature, the ratio of the relative change in the glass encapsulated NTC thermistor's dynamic zero power resistance to the temperature change that caused the change.
αT: Zero-power resistance temperature coefficient at temperature T (K).
T: Temperature (T).
B: Material constant.
Dissipation coefficient (δ)
Under the specified ambient temperature, the glass encapsulated NTC thermistor dissipation factor is the ratio of the power dissipated.
The glass package glass encapsulated NTC thermistor is also the MF58 series resistor, similar to the shape of a diode, with an axially tinned (copper-clad nickel-iron) wire. It is widely used in temperature measurement, detection, indication, monitoring, measurement, control, calibration, and compensation, etc.
What is the performance of the glass encapsulated NTC thermistor?
1. Good stability and high reliability
2. Wide resistance range: 0.5～1000KΩ
