  • What is NTC Thermistor?Page Browsing:8055

    IntroductionThermistors are a type of sensitive elements, and they are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients. The typical characteristic of a thermistor is that it is sensitive to temperature and exhibits different resistance values at different temperatures. Positive te...

  • What Are the Functions and Applications of the Varistor?Page Browsing:12346

    IntroductionVaristor, a resistive device with non-linear volt-ampere characteristics, which is mainly used to clamp a voltage and absorb excess current to protect the sensitive devices when the circuit is under overvoltage. Its English name is "Voltage Dependent Resistor" abbreviated as "VDR". Its resistor material is semiconductor, so it is a kind of semico...

  • How to Test Ground Resistance?Page Browsing:7548

    IntroductionThe ground resistance is a resistance that the current flows into the ground from the grounding device and then flows through the earth to another grounding body or diffuses far away. The value of ground resistance reflects the good degree of contact between electrical device and the ground and reflects the scale of grounding grid.This article mainly introduces how to test the ground r...

  • What is the giant magnetoresistance (GMR)?Page Browsing:14730

    IntroductionThe Giant Magnetoresistance (GMR) refers to the phenomenon in which the electrical resistivity of a magnetic material changes greatly when it has an external magnetic field as compared with the absence of an external magnetic field.It is a quantum mechanical effect that results from a layered magnetic thin film structure. This structure is formed by alternately laminating thin layers o...
