The V10E25AUTO is a popular metal oxide varistor (MOV) used in many applications that require surge protection from transient voltage spikes. This device is a multi-purpose device that can be used for a variety of applications including EMI/RFI filter, motor controller, arc fault sensing, and medical equipment.

The V10E25AUTO is a three-terminal variable resistor with a flat response curve. It is designed to protect circuits from transients and electrical spikes, by limiting the voltage that can pass through it, thus preventing damage to the connected components. When a transient voltage spike occurs, the device absorbs the excess energy, helping to maintain circuit integrity.

The V10E25AUTO has a very fast response time, which is crucial in protecting against transient voltage spikes. Additionally, it has a wide operating temperature range, with excellent thermal stability and low temperature drift. This makes it well suited for use in both indoor and outdoor applications.

The device is composed of a ceramic body, filled with a zinc oxide molded “donut-like” structure. This donut-like structure acts like an electrical resistor, absorbing and dissipating the transient energy. When the applied voltage exceeds the rated voltage of the MOV, the device can be triggered to provide protection by acting as a short circuit.

The V10E25AUTO is most commonly used in equipment that requires protection from surges associated with AC mains line power, such as TV sets, fax machines, computers, and other electronics. It is also often used in automotive applications due to its high current surge capability, particularly in sensitive electronics such as ECUs, ABS, and airbags.

The device is very easy to install and requires no tools or additional components; it simply needs to be connected between the power line and the protected equipment. It is usually mounted in close proximity to the protected device, as this will reduce energy losses and ensure the device performs as intended.

The V10E25AUTO is a reliable and cost effective means of obtaining surge protection for a variety of applications. It offers excellent thermal stability, fast response time, and reliable protection. By providing surge protection, it helps to ensure the safety and integrity of connected equipment, and prevent damage caused by transient voltage spikes.
