High Precision MF11 2Kohm 5% 3950 NTC Thermistor For Temperature Measurement

About us Of The NTC Thermistor For Temperature Measurement

AMPFORT Electronics is an early professional manufacturer of NTC thermistors in China. The company's NTC thermistors are widely used in various handheld devices and miniaturized electronic devices, as well as in various temperature measurement and temperature compensation occasions. The production of NTC thermistors has low price and high quality, and can completely replace foreign brands such as Murata, TDK, EPCOS and so on.

What's MF11 NTC Thermistor ?

The mf11 thermistor is called "thermal switch". After the current passes through the element, the temperature rises, that is, the temperature of the heating element rises. When the Curie point temperature is exceeded, the resistance increases, thereby limiting the increase of the current, so the decrease of the current causes the temperature of the element to decrease, and the decrease of the resistance value makes the circuit current. When the temperature increases, the temperature of the component increases, and it repeats itself, so it has the function of keeping the temperature in a specific range, and also plays the role of a switch. Using this temperature resistance characteristic to make a heating source, as a heating element, there are air heaters, electric soldering irons, drying cabinets, air conditioners, etc., and it can also protect electrical appliances from overheating.

The mf11 thermistor has the characteristic of sudden change of negative resistance. At a certain temperature, the resistance value decreases sharply with the increase of temperature, and has a large negative temperature coefficient. The constituent material is a mixed sintered body of vanadium, barium, strontium, phosphorus and other element oxides, which is a semi-glass-like semiconductor, also known as CTR as a glass-like thermistor. The sudden change temperature varies with the addition of oxides such as germanium, tungsten, molybdenum, etc.

When testing, use the multimeter ohm gear (depending on the nominal resistance value to determine the gear, generally R×1 gear), which can be operated in two steps: first, normal temperature detection (indoor temperature is close to 25 ℃), use alligator clips instead of test pens to respectively clip The actual resistance value of the two live pins is measured and compared with the nominal resistance value. If the difference between the two is within ±2Ω, it is normal. If the actual resistance value is too different from the nominal resistance value, it means that its performance is poor or damaged.

Heating test, on the basis of normal temperature test, the second step test - heating test can be carried out, a heat source (such as an electric soldering iron) is heated close to the thermistor, and the multi-function indicator is observed. Until the universal indication changes with the increase of temperature, it shows that the resistance value is gradually changing (the resistance value of the temperature coefficient thermistor NTC will become smaller, and the resistance value of the positive temperature coefficient thermistor PTC will become larger). When the resistance value changes to a certain value, the displayed data will gradually stabilize, indicating that the thermistor is normal. If the resistance value does not change, it indicates that its performance has deteriorated and cannot be used continuously.
