A varistor is an electronic component with a special purpose of protecting a circuit from high voltage or transient spikes. The most common type of varistor is the metal-oxide varistor, also known as a MOV. Metal-oxide varistors, or MOVs, are voltage-dependent resistors (VDR) that guard sensitive electronics from over-voltage transients on their power lines. ROV07H180M-2 is an example of an MOV that provides surge protection in various applications.

ROV07H180M-2 is an enhanced High Energy MOV (HE MOV) product from Littelfuse. It offers superior surge protection, low clamping voltage, and low dynamic resistance. It has a wide operating temperature range of -40°C to 105°C. The device is UL Recognized and features low leakage current, low EMI emissions.

ROV07H180M-2 has several distinct advantages that make it suitable for use in various applications. It features a high thermal stability and excellent surge capability, with an energy rating of 10kA (10 x 1000A). It is also capable of handling a large current capacity for a given size of device. The ROV07H180M-2 features a low capacitance of 0.28pF. Additionally, it has a low insertion resistance of 0.74 Ω in both directions.

ROV07H180M-2 can be used in a variety of applications. It is particularly well suited for use in power supplies, which are often exposed to over-voltage transients. The device can also be used in medical devices, telecommunications equipment, and consumer electronics. The low leakage current, high current capacity, and high energy rating make the ROV07H180M-2 suitable for such applications.

The ROV07H180M-2 works by limiting the flow of electricity when a high-voltage transient or spike is detected. When a voltage spike occurs, the MOV acts as a fuse, limiting the flow of current and dissipating the surge energy, thereby protecting the connected device. The MOV is designed to function quickly, typically within one to two nanoseconds.

When using the ROV07H180M-2, it is important to consider the total power and current rating for the device. The high surge voltage and peak current rating should also be taken into account when selecting the device. In addition, the MOV should be properly mounted to ensure adequate heat dissipation. Too much heat can cause the MOV to fail prematurely.

ROV07H180M-2 is an effective solution for circuit protection from high voltage or transient spikes. It features a low capacitance, a low insertion resistance, and a high energy rating, making it well suited for a variety of applications. The device has a fast response time, typically within one to two nanoseconds, and a high level of surge protection. Additionally, the MOV must be properly mounted and its ratings taken into consideration for the best protection.
