This component is particularly well suited for automobiles due to its high temperature and vibration tolerance. With such a broad application spectrum, theVK103MM151R006P050 is widely used and relied upon to protect electronic systems from overvoltage damage.

Working Principle

The VK103MM151R006P050 is designed to suppress polarity and noise in a system, and protect individual components from voltage spikes. The VK103MM151R006P050 is built with a metal oxide varistor (MOV) to absorb any sharp transients or peaks, and a varistor to provide a resistance against continuous overvoltage. A capacitor within the unit assists the device to handle any ripple current present.

The MOV is a leadless chip which is composed of metal oxide particles and ceramic binder. These particles are pressed into a solid contact powder, and to increase their surface area, the particles are sintered to create a composite material which exhibits noise and overvoltage clamping. The capacitance value of the MOV helps to clean out and reduce any residual noise to maintain the integrity of the signal. The varistor, on the other hand, offers a rapidly increasing resistance to any overvoltage, effectively limiting the level of voltage we across the system.

The VK103MM151R006P050 is designed to protect electronic systems from high voltage surges. The component is tuned to the needs of a particular system, and will shield any vulnerable components within the system from the harmful effects of a voltage surge. The VK103MM151R006P050 provides excellent protection, allowing the system to perform at optimal levels.
