Precision MF52 Small Black Beads Epoxy ntc Resistance

Product Item: Precision MF52 Small Black Beads Epoxy ntc Resistance
Category: NTC
Thermistors are semiconductor electrical components made from metal oxides of transition elements (from titanium to copper in the periodic table). Its electrical conductivity is between the conductor and the insulator; And it decreases sharply with increasing temperature. Generally, when the temperature changes by 1 ° C, its resistance changes from 2% to 6% of the original resistance, which is about ten times larger than the temperature coefficient of ordinary metal conductors (for example, the temperature coefficient of platinum is 0.42%). So it can be used as a temperature sensitive element.

   When measuring NTC thermistors, the following must be observed:
• Can not be measured in air, The temperature difference in the air is bigger, Measurement is not accurate, Resulting in accuracy bias.

• Measurement using a high-precision thermostat, NTC into the thermostat after the test tank, After the temperature of the thermostat is stable, Can be measured.
• Measure voltage as low as possible,To reduce NTC self-heating caused by measurement error.
• For high temperature measurements,The temperature of the bath needs to be corrected and checked with a thermometer.
