I Description Of The MF75 Super Power NTC Thermistor
Inrush current is the momentary surge of current created when power is turned on to motors,transformers,power suppliers and heating elements. The more power required by industrial equipment,the larger the inrush current. It can effectively quench the inrush current by means of in series with power NTC thermistor in return circuit of power supply.

Radial Leaded Ultra Big Power NTC Thermistor MF73 For Switching Power Supply
I Description Of The Ultra Big Power NTC Thermistor MF73
High-Power NTC Thermistors are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.
Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment.
II Application Of The Ultra Big Power NTC Thermistor MF73
* All kinds of power supply,UPS power supply,Switching power supply

The thermistor method, unlike the previous examples, uses heat detection to activate. The alarm activates once the thermistor detects a high temperature. Thermistor temperature detection doesnot require smoke to activate and has fewer false alarms. The thermistor uses the ambient temperature of a building and will only activate when that temperature increases exponentially. The thermistor method is reliable in this fire alarm example as there would be few false alarms and a quicker alert rate, but the thermistor method is also versatile.

The latest products relates to a chip-type glass-encapsulated negative temperature coefficient thermistor. It has a glass shell, a thermistor chip and two metal electrodes. The metal electrode is a SMT type, and thermistor chip is fixed in a glass shell. Two metal electrodes are installed at both ends of the glass shell. The metal electrodes at both ends are respectively connected to the electrodes on both sides of the resistance chip through a conductive body integrated with the metal electrode, and the conductive body and the resistance chip are encapsulated in a glass case at a high temperature. The utility model is electrically connected with the outside world through a metal electrode, and the installation space is smaller, the installation is more convenient, the lead-free bending is not easy to damage the product when the installation.
low cost glass encapsulated thermistors are manufactured using super stable NTC chips which are hermetically sealed in a glass diode package. See more.

What are PTC thermistors made of?
Most PTC thermistors are made from doped polycrystalline ceramic (containing barium titanate (BaTiO3) and other compounds) which have the property that their resistance rises suddenly at a certain critical temperature. Barium titanate is ferroelectric and its dielectric constant varies with temperature.
Characteristic
high precision NTC thermistors
Small size, Fast response
Steady Operating for long time
Good quality of copherence and interchange
Scale production, high ratio of features to cost
This is a property of a Negative Temperature Coefficient resistor (NTC ).
There are also thermistors that have Positive Temperature Coefficient (PTC for short) which means as the temperature increases, the resistance increases. However, PTC thermistors have a sort of tipping point and greatly change the resistance at some temperature. This makes the PTC thermistor a little harder to interface with. For this reason, for most low-cost temperature measurement, NTC thermistors are preferred.
For the remainder of the article, you can assume we'll be referring to NTC type thermistors.
Knowing the temperature in a project can a very useful piece of data to have handy. Knowledge of temperature can help regulate room temperature for a comfortable environment, ensure that a 3D printer bed is hot enough for materials like ABS to stick to its surface, prevent engine overheating, and keep food from being burnt.
For this article, we are only concerned with one type of sensor that can measure temperature. This sensor is called a thermistor.
