MOV (Varistor) is important components which helps in surge protection. It protects electronics appliance against lightening surge. A good knowledge plays important role in MOV selection. Below video explains step by step calculation for MOV selection. After watching this video i am pretty sure that you will be able to select the MOV as per your specification. IEC6100-4-5 defines the surge immunity level. Thanks !  

                                            Electrostatic Discharge Electrostatic Discharge (ESD) is the abrupt release of charge from one object to another.  Such a discharge can permanently damage or otherwise upset the function of sensitive electronic circuits. All electrical/ IT/ Medical equipment's are tested for ESD immunity to insure their continued reliable operation if subjected to realistic levels of ESD after being placed in service. For more details please watch below video. This video will help you to understand the below topics. -ESD overview -ESD Design Technique -ESD Circuit Design Guidelines -ESD Layout Design Guidelines -ESD Troubleshooting Technique Thanks !

                                                      EMI & EMC Overview Definition [IEC 61000-1-1] The ability of a device, unit of equipment, or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment. A system is said to be electromagnetic compatible if  It does not cause interference with other systems It is not  susceptible to emission from other systems It does not cause interference with itself. For more details about EMC please watch this video. This will help you to understand the basics about EMC. It will also help you understand about EMI. Thanks !
