9401780000

A varistor (also known as a voltage-dependent resistor or VDR) is a type of resistor whose resistance changes or adapts with the applied voltage. Typically, the resistance decreases with increasing voltage. Varistors are used in clamps, transient voltage suppressors (TVS), and other voltage-dependent circuits and devices. The 9401780000 is a TVS-varistor specifically designed to protect electrical circuits against overvoltage transients, such as from lightning, motor start up, and power discontinuities.

The 9401780000 combines two components to provide superior transient protection. The first component is the varistor. It is designed to reduce the voltage to acceptable levels during an overvoltage transient. The second component is the MOV--metal oxide varistor--which provides energy absorption and protects the varistor during the transient. It combines with the varistor to absorb the energy generated by an overvoltage surge.

The 9401780000 works by providing two functions: shunting the current and dissipating the energy from a transient. The varistor shuns the current from the protected circuit to ground, thus limiting the amount of energy entering the protected circuit. The MOV dissipates the remaining energy, protecting both the transformer and the varistor. The 9401780000 is designed to work with high-frequency protection devices, such as flyback transformers, to enhance the performance and reliability of the circuit.

The 9401780000 can be used in a variety of applications for overvoltage protection. It can be used in commercial and industrial applications, including power supplies, lighting systems, networks, and communications equipment. It can also be used in automotive applications, such as engine control systems, ABS brake systems, multiplex systems, and other critical applications. The 9401780000 is ideal for applications where overvoltage protection is needed at high frequencies, such as server and data center applications.

The 9401780000 has a wide range of working parameters and can be customized for various applications. It is designed to provide protection against overvoltage transients of up to 132 volts peak and is rated for working voltages of up to 25 volts continuous. It can operate in temperatures from -40°C to 125°C and is RoHS compliant. The 9401780000 is offered in a variety of package sizes and materials to meet the needs of various applications.

The 9401780000 is an effective and reliable overvoltage protection solution for both commercial and industrial applications. It combines varistor and MOV protection to reduce the damage caused by overvoltage transients. Its wide range of working parameters make it suitable for a variety of applications. And it is RoHS compliant, making it a great choice for the most demanding applications.
