MF11 compensated thermistor
NTC (negative temperature coefficient) thermistor is a heat-sensitive semiconductor resistor whose resistance value decreases with the increase of temperature, and the resistance temperature coefficient is in the range of -2%/k~-6%/k, about 10 times that of the metal resistance temperature coefficient. The change in the resistance value of the NTC thermistor can be caused by the change in the external ambient temperature, or it can be caused by the flow of current and its own heating. Its various uses are based on this property. NTC thermistors are composed of polycrystalline ceramics with mixed oxides. The conductive mechanism of this material is quite complex.
Dongguan Linkun electronic Technology Co., LTD is the domestic earlier production NTC thermistor professional manufacturers, the company produces the NTC thermistor is widely used in all kinds of handheld devices and miniaturization of electronic devices, are widely used in all kinds of temperature measurement and temperature compensation, the company production of NTC thermistor with low price, good quality, It can completely replace foreign brands such as Murata, TDK and EPCOS. 1. The scope of application: used for temperature measurement and general accuracy in measuring equipment, temperature compensation of transistor circuit. 2. Characteristics: MF11: B value error range is small, the resistance error range in 5% of the products, its consistency, good interchangeability. MF12: a wide range of impedance values maximum nominal resistance up to 2 m, stability is good.
