TVS - Varistors, MOVs

MOV-20D330KTR offers surge protective technology, which is an important factor in overall system reliability. This overvoltage suppression device is a metal oxide varistor (MOV) with a rated voltage of 330 volts. It is designed to protect a circuit or system from voltage transients or surges that can damage system components.

Application Field

MOV-20D330KTR is suitable for a variety of applications and circuits including air conditioners, industrial equipment, power supplies, inverters, pumps, and lighting. It can handle surges as high as 30 kV as per IEC61000-4-5. MOV-20D 330KTR has excellent clamp characteristics that allow it to perform in high-speed transient response applications. It is also widely used in automotive, home automation, communications, and consumer electronics. It is designed to provide reliable and effective ESD protection for electrical and electronic systems.

Working Principle

MOV-20D330KTR works on the principle of overvoltage control and protection. It is a nonlinear, voltage dependent resistor whose resistance decreases with an increase in voltage. The MOVs are designed to quickly respond to a voltage surge by taking any excess voltage away from the circuit. When the surge is over, the MOV automatically reverts back to its normal resistance level, thus allowing the power to flow across the circuit without interruption.

It is manufactured using metal oxide material, which is sensitive to changes in voltage levels and has an inherent ability to dissipate more current than normal resistors. This allows the MOV to handle high-energy pulses with ease. The MOV is composed of metal electrodes that conduct the energy of the transient surge and are separated by an oxide-based composition. When the voltage of the surge exceeds the rated breakdown voltage, the electrons in the oxide material are excited and conduct current to the other electrode.

The ability to dissipate current makes MOV-20D330KTR an ideal choice for ESD protection. The device is able to quickly and effectively ground any excessive voltage spikes, thus eliminating any hazard to connected equipment. Moreover, MOV-20D330KTR has a long life as it is able to withstand mechanical and electrical shock. It is able to survive temperatures ranging from -40°C to 85°C and is resistant to mechanical shock and vibration.

MOVs have become an integral part of many power-supply and ESD protection applications. Its high energy-handling ability makes it a desirable choice as it is able to provide reliable and effective protection in a variety of applications. MOV-20D330KTR has become an industry standard for ESD protection, and as a result, it is used in various power systems, communication systems, consumer electronics, automotive, and more.
