ROV10-511K-S

TVS - Varistors, MOVs

The ROV10-511K-S is a popular Varistor and MOV series used in various applications. Varistors and MOVs (Metal Oxide Varistors) are two commonly used components that are used in transient voltage suppression (TVS) devices. A Varistor is a voltage-dependent resistor, and an MOV is an active device that limits transient voltage spikes by diverting them to ground.

The ROV10-511K-S is composed of different elements that combine to provide features such as low capacitance and high ratings for voltage pulse protection, surge current protection, and ESD protection. In terms of construction, the device consists of zinc oxide (ZnO) in an octagonal encapsulation. This encapsulation provides increased speed and better thermal and electrical properties. It is also fairly light in weight. In addition, the device has high surge capability, fast response times, and good performance in temperature ranges from -55°C to +175°C.

The ROV10-511K-S is designed to work at the junction of the TVS device\'s positive and negative inputs. It is normally connected between the power source and the load to protect the load from transient voltages. The device is equipped with a terminated lead wire that is designed to absorb and disperse the electrical surge and limit the voltage spike from being too high or too low. This protects the components connected in the circuit from overvoltage failures. It also reduces the duration of the transient current and the peak value of the current.

The ROV10-511K-S Varistor and MOV series is used in a wide range of applications, including automotive, industrial, computer, and telecom applications. In automotive applications, these devices are used to protect against transient voltages and inrush currents that are caused by start-up and turn-off of the engine. In industrial applications, they are used to protect sensitive components such as printed circuit boards and integrated circuits from overvoltage and overcurrent situations. In telecom applications, the device is used to protect circuitry from power surges and transients.

The working principle of the ROV10-511K-S Varistor and MOV series is based on the principle of transient voltage suppression (TVS). The device works by diverting the transient voltage and current spikes to ground when they exceed their rated value. When a voltage transient occurs, the device quickly diverts its current and voltage to ground. This reduces the power level of the transient and prevents damage to the surrounding components. As the transient passes through the device, the Varistor and MOV absorb the energy and dissipate the Heat. In this way, the device protects the power circuitry from damage and extends its life.
