Electronic components and materials play an important role in the process of circuits and systems in various electronic fields. Varistors, also known as voltage dependent resistors (VAR), are the most typical of all the components for TVS (transient voltage suppression). AVR-M1005C120MTAAB is one type of transient voltage suppressor (TVS), with its application field and working principle.

AVR-M1005C120MTAAB is characterized by its low-standing basic capacitance, high surge attitude and a very stable response in fast transient applications. The advanced multi-layer coating provides superior moisture and corrosion resistance while still maintaining high temperature ratings. The package type of AVR-M1005C120MTAAB is surface mount of 0201 size and its capacitance is 1.2pF.

This type of varistor is mainly used in mitigating EFT (electrical fast transient) surges generated by cables, connectors, relays, contact points, and other electrical equipment. Its application field involves electronic systems for testing, measurement and control, and electronic medical systems. It can protect many applications such as TVS diodes, ESD (electrostatic discharge) protection, EMC (electromagnetic compatibility) protection, and lighting applications.

AVR-M1005C120MTAAB is suitable for protecting equipment and components from overvoltage transient, EFT and ESD on telephone lines, power lines, computer systems, video systems and medical equipment. It is designed specifically to meet common, industrial, and automotive requirements, including: 1.9V RS, 8.5V IS, 12V PP, 18V CC and 24V RS.

The working principle of the varistor lies in its behavior reverse to that of a capacitor. When a varistor\'s voltage is lower than breakdown voltage, its resistance will decrease rapidly; for instance, a 10V varistor has only about 8.5 Ohms resistance before it reaches 10V, and after 10V it has about 140 ohms in resistance. When the voltage drops to 6V, the resistance will be about 35 ohms. Therefore the varistor can be used to absorb overvoltage or increase the load of the circuit.

AVR-M1005C120MTAAB is featured by its low voltage and current absorption, excellent response speed and wide operating voltage range. The response time is over 0.3ns and its operating voltage range is from 11V to 130V. Furthermore, it has excellent surge absorption attitude with peak current of 4.2A and 400W surge rating (8/20μs).

In sum, AVR-M1005C120MTAAB is a widely applicable varistor with high-degree protection for a vast range of electronic systems. Its well-developed low-capacitance contributes to an ideal performance when conducting transient currents. By providing excellent surge absorption, it ensures a high-precision level of protection and accuracy for the surrounding electronic devices.
