Metal oxide varistors are essential components for protecting electronic circuits from surge current. Understanding their key parameters and testing methods is crucial for ensuring their reliability and effectiveness. By following the outlined testing procedures and selecting varistors with appropriate parameters, engineers and technicians can enhance the protection of electronic systems. Understanding the parameters and proper testing methods of MOV varistors is essential for their effective application. Key parameters include maximum clamping voltage, surge current capacity, leakage current, and nominal voltage. Testing methods involve varistor voltage testing, leakage current testing, clamping voltage testing, surge current capacity testing, etc.

Selecting the right NTC thermistor involves careful consideration of the maximum working current, nominal resistance value, ntc thermistor beta value and thermal characteristics. Understanding these factors ensures optimal performance and longevity of the NTC thermistor in various applications. By considering additional factors like maximum rated voltage, filter capacitor value, allowable startup current, and environmental conditions, engineers can make informed decisions to enhance the reliability and efficiency of their electronic designs.
