A MOV-14D470K is a common type of Metal Oxide Varistor, also known as a MOV. It is a voltage-dependent resistor which is designed to protect electronic circuits from problems caused by voltage spikes. MOVs are primarily used in electronics applications such as power supplies, data lines, and electrical motors. In this article, we will discuss the application field and working principle of a MOV-14D470K.

The MOV-14D470K is a Metal Oxide Varistor designed for applications requiring a surge current handling capability of 14kA. It has a maximum working voltage of 470V AC or DC. This MOV has a maximum, allowable voltage rating (VAR) of 660V. It is constructed with a zinc oxide-based compound sandwiched between two metal plates, and it is encased in an epoxy resin. The metal plates are usually composed of zinc and/or an alloy of zinc and nickel. The MOV-14D470K is designed to be used in temperatures ranging from -40°C to +85°C.

MOV-14D470K application includes protecting electrical circuits from damage caused by power spikes, electric noise, and other voltage transients. It is commonly used in power factor correction circuits, power supplies, data circuits, motor control circuits, and surge protection devices. The MOV is also used in high voltage and high current applications such as electric transformers, electronic motors, and power supplies.

The MOV-14D470K works by providing a low impedance path for the current surge. This low impedance reduces the voltage of the surge to a safer level. The working principle of the MOV is based on its electrical characteristics, which are such that the resistance of the MOV increases as the voltage across it increases. When the voltage spike exceeds the rating of the MOV, the voltage is limited by the increased resistance of the MOV.

MOVs are designed to limit the voltage to specified levels. They are designed to take the brunt of voltage surges, thus protecting the devices they are connected to. When a voltage surge greater than the voltage rating of the MOV is encountered, the device will clamp the voltage to the specified levels. The MOV will saturate and lose its ability to reduce voltage after the voltage level exceeds the MOV rating, thus protecting the connected device.

The MOV-14D470K is a comprehensive and reliable Component which helps to protect circuits from voltage surges and other transients. It is designed to provide high current surge protection and is suitable for use in a wide range of applications. The MOV-14D470K has a maximum working voltage of 470V AC or DC, and a maximum, allowable voltage rating (VAR) of 660V, suitable for a variety of applications requiring high current surge protection.
