The ROV05-471K-S-2 is an ultra-low capacitance ESD suppressor designed for a variety of end-use applications. It is a two-terminal Type II V-chip (VDR) varistor with a surface-mount leadframe. It is designed for ESD protection with low working voltages, a low operating temperature range and excellent clamping capability.

The ROV05-471K-S-2 is categorized as a TVS (Transient Voltage Suppressor) and a MOV (Metal Oxide Varistor). It works by using a semiconductor chip to absorb energy from spikes and quick transients such as electrical transients that might result from electrostatic discharge (ESD). The chip works as a two-terminal high voltage safety device that clamps a wide range of voltage transients.

TVSs and MOVs are used to protect sensitive electronic circuitry from destructive voltage spikes and other forms of overvoltage transients. These transients can be caused by induction, capacitive coupling, lightning, static electricity or an electrostatic discharge. The ROV05-471K-S-2 ESD suppressor helps protect against extreme overvoltage transients by providing a quick and stable discharge path to ground. The device is designed to function at a precise voltage while effectively absorbing ESD energy at much higher levels.

The ROV05-471K-S-2 varistor is constructed of multiple layers of a highly conductive ceramic material that is sandwiched between two thin layers of an electrode material. When a transient or surge occurs, the ceramic material instantly expands and forms a high-impedance path around the exposed electrode. This high-impedance path clamps the voltage and diverts it away from the sensitive components. The varistor then returns to its original, undeformed size, which enables the mechanism to reset itself and continue to provide protection.

When selecting a surge suppressor, it is important to consider the maximum working voltage. The ROV05-471K-S-2 ESD suppressor has an operating voltage of 470 Volts AC, so it is suitable for protecting most sensitive electronic components. In addition, it has an operating temperature range of -20°C to +85°C, so it is ideal for many industrial applications.

The ROV05-471K-S-2 ESD suppressor is simple to install and can be surface mounted to reduce space requirement. The varistor is designed to provide effective ESD protection in a variety of applications, such as consumer electronic products, industrial machines, and telecommunications equipment. It can also be used as a surge suppressor for DC motor drives, signal lines, and other critical components in mission-critical applications.
