It is suitable for use in applications that require protection from high voltage surges and transients. In automotive applications, the varistor is typically used to protect automotive electronic devices such as radios and in-car entertainment systems from damages caused by power surges.

In industrial control and telecommunications applications, the varistor provides protection from high energy surges. It is also used to protect circuit boards from potential damage when circuits are switched on or off. The versatility of this varistor makes it suitable for a wide range of applications.

In appliance applications, the varistor can be used to protect circuits from high voltage spikes, as well as from electromagnetic interference and radio frequency interference (EMI/RFI). In audio/visual electronics, the varistor is used to provide protection from DC power supply over and undervoltage transients.

Working Principle

The working principle of the AMCV-0603-090-C180N-T Varistor is based on the piezoelectric effect. The piezoelectric effect is an electrical property of certain materials, which causes them to deform in an electric field. The material used in this varistor consists of a metal shell and core, which contain a ceramic multilayer structure. The ceramic structure has a high electrical resistance and is also able to generate an electrical field.

When an external voltage is applied to the varistor, the piezoelectric effect causes the ceramic layers to deform which increases its electrical resistance. This increases the resistance to current flow and the varistor is able to absorb the energy of the surge, preventing high energy transients and surges from damaging the circuit. It is also able to act as a ground connection to help reduce the magnitude of a surge or transient.

The thermally protected feature of the AMCV-0603-090-C180N-T prevents it from overheating due to high energy transients and surges. When the varistor reaches its maximum temperature, the thermostat will open, cutting off the connection and preventing it from further damage.

Conclusion

The AMCV-0603-090-C180N-T is a versatile, thermally protected Varistor with a Clamping Voltage of 180V. It is suitable for a wide range of applications, including automotive, industrial control, telecommunications, appliance, and audio/visual electronics. Its working principle is based on the piezoelectric effect and it is able to absorb the energy of transients and surges, preventing them from damaging the circuit. The thermally protected feature ensures that the varistor does not get damaged by overheating. Thus, the AMCV-0603-090-C180N-T is an ideal choice for any application requiring protection from high voltage surges and transients.
