{411} What is MOV, Metal-Oxide Varistor, VDR, TVS

in this video {411} What is MOV, Metal Oxide Varistor, VDR, TVS, i discussed What is MOV, Metal Oxide Varistor, VDR, TVS
Metal oxide varistors, also known as MOVs is a voltage dependent resistor. They are voltage dependent, its non-ohmic behavior provides transient suppression. MOVs are composed primarily of zinc oxide with small additions of other metal oxides. The structure of the body consists of a matrix of conductive zinc oxide grains separated by grain boundaries. These boundaries are responsible for blocking conduction at low voltages and are the source of the nonlinear electrical conduction at higher voltages. The use of a metallic oxide within their construction means that MOV’s are extremely effective in absorbing short term voltage transients and have higher energy handling capabilities. As with the normal varistor, the metal oxide varistor starts conduction at a specific voltage and stops conduction when the voltage falls below a threshold voltage. it is also known as transient voltage surge suppressor, it is used to protect any circuit from over voltage spikes

hello Haseeb...can i connect an mov and a thermistor in parallel? i have an 10D471K and an SCK2R56 for surge protection? thanks.

Thanks for the tutorial. This component gave me hell when I just started repairing.

[@shakilahmed591]

[@DojuMelody]

Sir is it ok if 14D511K VDR resistor is replaced by AH332M VDR resistor? Does it make much difference to the function?

[@ravikumarjoshi2085]

Sir, your explanation on MOV clears my all doubts about use of it in various circuits. Please explain the use of X class and Y class capacitors as EMI & RFI filters in power supplies.

Merci Mr hasseeb pour cet excellent travail.ma question est:pourquoi le varistor d'une carte électronique de frigo n'a pas fonctionné lors d'une surtension?tous les composants après ce varistor ont grillés.sa valeur est pourtant 670volts(D671).merci

[@HaseebElectronics]

le bienvenu mon cher. tout d'abord désolé d'apprendre la perte. car ces dispositifs de protection doivent arrêter la surtension, mais dans certains cas, ils ne parviennent pas à attraper les petites pointes ou parfois la surtension est inférieure à son niveau d'énergie nominal. ou parfois, il n'y a pas de surtension, et le circuit de commutation sur la carte démarre en "facteur de sonnerie du filtre EMI" ce qui endommage les pièces associées il existe de nombreuses possibilités de catastrophe dans la technologie électronique moderne

[@gerandpontrac2760]

Merci beaucoup pour cette réponse convaincante.que dieu vous protège.

[@stephenwawrzyniec6719]

[@arshadiqbal4809]

Which protective device is useful for spikes of less than 10nsec. I have used MOVs but that don't respond such spikes.

[@HaseebElectronics]

in input try to use X & Y rated capacitor set, and set EMI filter with some good attenuated with acceptable corner frequency, then MOV or TVS unidirectional or bi-directional,
