PPTC resettable fuse Current Fuse Ceramic PTC Overload Protector is an overcurrent protector.Because the use of different materials, the function is also very different. 1) polymer PTC reset fuse and the most obvious difference between the g....
A thermistor is a component of a semiconductor ceramic working body that is very sensitive to temperature.Compared with the commonly used metal resistance,It has a much larger resistance temperature coefficient value.According to the differe....
NTC Temperature Characteristics Symbol: R = Ro exp {B (I / T-I / To)} R: resistance value at temperature T (K) Ro: Resistance value at temperature T0 (K) B: B value * T (K) = t (C) +273.15 In fact, the B value of the NTC thermistor is not co....
structure--With manganese (Mn), cobalt (Co), Nickel (Ni), copper (Cu), aluminum (Al) metal oxide (with semiconductor properties), or silicon carbide (SiC) ceramic material such craft.Advanced. characteristic--The resistance value is inversel....
The voltage and current of the zinc oxide varistor are in a special nonlinear relationship.When the voltage across the voltage equals or exceeds its sensitivity,The resistance will be from infinity, quickly reduced, similar to the short circ....
Varistor current and voltage in a certain range, the resistance value with the voltage change.In Taiwan, it is called a surge absorber, or an electric shock (surge) suppressor (absorber).Varistors have been widely used. Varistors have differ....
Positive Temperature Coefficient Thermistor Material Structure - It is made of barium titanate (BaTiO3), strontium (Sr), zirconium (Zr) and other materials. The positive temperature coefficient thermistor belongs to the direct thermal type t....
Thermistor main parameters:In addition to the nominal resistance, rated power and allowable deviation and other basic indicators,As well as the following indicators parameters: 1) Measuring power (W):Refers to the specified ambient temperatu....
The intake air temperature sensor is a negative temperature coefficient thermistor,Intake air temperature sensor is also a two-wire sensor,Installed in the intake pipe or air flow meter. Intake Air Temperature Sensor, IATS installed in the i....
1, varistor is a zinc oxide as the main component;Metal oxide semiconductor nonlinearity, limiting voltage resistance。 The volt-ampere characteristics of the varistor are continuous and incremental,So it does not exist continued flow, cut....
