MOV-07D751KTR is a gaseous metal oxide varistor (GMOVP), usually divided into three categories based on its different structures, which are AC MOV, DC MOV, and Surge Current Absorption MOV. It is a non-linear resistor with a resistance that changes in accordance with the voltage.

The MOV-07D751KTR has a wide application field, it is mainly used for protection against overvoltage in AC circuit and in DC circuit, and is suitable for surge current absorption for their low reactance, it is often seen in various kinds of power supplies, computers, security equipment and telecom systems.

The working principle of MOV-07D751KTR is based on its special non-linear resistance carrier - zinc oxide, which can prevent current flowing in the reverse direction and change its resistance depending on its bias voltage. At low voltages, the resistance of the MOV-07D751KTR is very low, allowing for maximum current flow. As the bias voltage increases, the resistance increases exponentially, at a certain voltage the resistance is so great that current cannot pass, protecting the circuit from overvoltage.

The MOV-07D751KTR also has other advantages, such as:

• High temperature resistance: it can operate in temperatures ranging from -55°C to 150°C;
• Small size: it is small and has low power dissipation, which is very suitable for miniature and high-density design;
• High response rate: the response rate is fast, which can protect the circuit in a few nanoseconds after overvoltage.

MOV-07D751KTR is widely used in power supplies, computers, security equipment and telecom systems. Its wide application field and high working performance make it a reliable component for device protection.
