Varistors, also known as voltage-dependent resistors (VDRs), are two-port electrical components with a highly non-linear variable resistive characteristics. The device has a voltage-dependent operating range which is controlled by a relationship between the applied voltage and the resulting current. Varistors are typically used in power systems for surge protection and are available in a wide variety of sizes and configurations, including radial-leaded, axial-leaded, and surface mounted packages.

The ROV20-330M is a voltage-dependent varistor which exhibits excellent transient current suppression characteristics over a wide range of voltages. The device is temperature rated from -55°C to 125°C, and features a working voltage range of 5 VDC to 330 VDC and a working current of 15A. Its ultra-low capacitance makes it suitable for a variety of applications requiring extremely low leakage current. ROV20-330M varistors are available in radial-leaded, axial-leaded, and surface-mounted packages and are lead-free and RoHS compliant.

The ROV20-330M is mainly used for efficient protection against overvoltage transients in power distribution systems. It can be used to protect DC-DC converters, AC supply lines, and other critical applications from potential transient surges. It is also suitable for RF applications as it has a very low capacitance. This device is suitable for high-temperature applications up to 125°C and can even provide reliable protection against sudden overvoltage transients in extreme conditions.

The working principle of the ROV20-330M is quite simple. It uses a Zinc Oxide-based ceramic material to produce a variable resistor that increases its resistance as the applied voltage increases. When the voltage reaches the device’s working voltage threshold, it will start to conduct, thereby limiting the current flow and providing surge protection.

The Zinc Oxide-based varistor material of the ROV20-330M exhibits a very gradual transition in conduction resistance when exposed to varying voltage levels, allowing the device to provide reliable overvoltage transient protection even in harsh operating environments. The device’s temperature ratings up to 125°C ensure that it can provide reliable protection even in extreme conditions. The ROV20-330M is designed to allow for quick response time when exposed to transient voltages, providing reliable surge protection even for very fast transients.

The ROV20-330M is a versatile device that can be used in a wide variety of power protection applications. It is suitable for a wide range of voltages and is capable of providing quick and reliable surge protection even in high-temperature and extreme operating environments. Its low capacitance makes it an ideal choice for RF applications, while its Zinc Oxide-based material ensures gradual conduction resistance, allowing for reliable protection against transient voltages.
