TVS - Varistors, MOVs:

ROV05-751K varistor is a voltage-dependent resistor made of metal-oxide material, and it belongs to TVS - varistors, MOVs. It is widely used in industrial, automotive, communication, LED lighting and other fields. This paper mainly introduces its application field and working principle.

Application Field of ROV05-751K:

ROV05-751K varistors are widely used in industrial applications for its high performance with superior capacity, excellent thermals, strong EMI, and easy to design. This kind of varistor is used as components in many safety circuits, and it can also be combined with other components, forming a bridge, which can be used to protect against both over-voltage (transients) and under-voltage (low power). It is usually used for surge suppression and spike protection in industrial equipment, computer and communication systems and other electrical and electronic products. Besides, ROV05-751K is also suitable for various devices related to automotive, communication, electromagnetic compatibility, LED lighting, etc.

Working Principle of ROV05-751K:

ROV05-751K varistor is made up of metal-oxide material with high electrical resistivity. The varistor has a very low resistance when the direction of current is normal, however, when an excessive current in the reverse direction is passed through the varistor, its resistance becomes very high due to the breakdown of the electric field. This process is called “voltage-dependent resistors” and it becomes the most important part of the varistor. In addition, the varistor has a “voltage-dependent resistance”, which means that its resistance changes according to the applied voltage. The resistance increases as the voltage increases.

ROV05-751K varistor can also absorb and dissipate the energy of surges and reduce the voltage of over-maximum. Its metal oxide material makes it have excellent capacity of absorbing and dissipating energy. At the same time, the varistor has a lower clamping voltage and helps reduce the clamping voltage of the system in the case of large over-voltage. Thus, it can protect the device against over-voltage damage and work as a protector in industrial and electronic fields.

Conclusion:

ROV05-751K varistor is made up of metal-oxide material, belonging to TVS-varistors, MOVs.It has a high performance and can be used to protect against over-voltage, under-voltage, surges, and spikes.ROV05-751K varistor has wide application fields in various electrical and electronic products, especially in industrial, automotive, communication, LED lighting, etc. Its working principle is related to the "voltage-dependent resistors" with a resistance that changes according to the applied voltage.
