TVS (Transient Voltage Suppressor) is a type of component used in sensitive electronics to protect the circuit from transient voltages or surges. Transient voltages, also known as transient over-voltage, are sudden and rapid increases in voltage that can damage and disrupt the operation of a circuit if not addressed. Varistors, also known as metal-oxide varistors (MOVs), are one type of circuit component used to protect circuits from transient voltages. The ROV07-471K is a popular MOV component used in a variety of applications, and this article will explore its application field and working principle.

The ROV07-471K is an MOV component rated for AC transient voltages of up to 1400V and pulses up to 16A. Its surge current capacity is 4700W at 8/20us. It has an operating temperature range of -55°C to +125°C, making it well suited for use in high-temperature environments. This rugged component is also highly resistant to corrosion, making it suitable for use in harsh, wet, and corrosive environments. It is well suited for use in consumer electronics, motor controllers, power supplies, and other sensitive circuits.

The ROV07-471K is an MOV component with an asymmetrical construction, consisting of a base element composed of zinc oxide and a coating of metallicfilm. The base element is polarized with a positive polarity on one sideand a negative polarity on the other. When a transient voltage is appliedto the component, the movable side of the element will pull the beads onthe opposite side towards it, and this expands the component to act as aswitch. This redirects the transient voltage away from the circuit, thus preventing damage and disruption from the transient over-voltage.

The ROV07-471K is a popular MOV component for many applications because of its high surge current and its wide operating temperature range. It is an economical way to protect sensitive electronic circuits from transient over-voltages, and its rugged construction makes it ideal for use in harsh, wet, and corrosive environments. The component’s asymmetrical construction allows it to quickly and effectively redirect transient voltages away from the circuit, and the zinc oxide base element provide excellent heat and electrical conductivity.

In summary, the ROV07-471K is an MOV component used to protect circuits from transient over-voltage. The component is rated for AC transient voltages of up to 1400V and pulses up to 16A. Its surge current capacity is 4700W at 8/20us. The ROV07-471K is constructed with an asymmetrical base element of zinc oxide and a metallic film coating. When transient voltages are present, the element will expand to act as a switch and route the transient voltage away from the circuit. The component’s robust construction, wide temperature range, corrosion resistance, and relatively low cost make it a popular choice for many applications requiring protection from transient voltages.
