A varistor is a type of voltage-dependent resistor. The voltage-dependent resistor, commonly referred to as a varistor, is an electrical component that limits the voltage across its terminals to a certain level. Varistors are mostly used to protect sensitive electrical components from damage due to voltage surges. The most common type of varistor is the Metal Oxide Varistor (MOV). The MOV, also known as the Metal Oxide Variable Resistor, or MOV type, is a voltage dependent resistor with a specifically designed construction of metal oxide layers, which change the resistivity of the device when a voltage is applied (or vice versa). MOVs are widely used in many applications because they provide protection against overvoltage conditions, such as voltage spikes, surges, transients and short-circuits.

The V250LA10 is a V Series Varistor manufactured by Bourns, Inc. It is a 11 mm, radial leaded disc-type varistor. The V250LA10 is most commonly used to provide overvoltage protection in automotive, consumer, and industrial applications. It has a 250 V Maximum Working Voltage rating, making it ideal for applications that require high surge protection.

The V250LA10 is constructed with a metal alloy core, and a zinc oxide ceramic coating. When a voltage is applied to the varistor, the ceramic coating allows electrons to move freely, thus increasing its resistance. This decrease in current helps protect any electrical components connected to the MOV from potential damage due to voltage surges.

The V250LA10 is rated for a maximum surge current of 10 kA 8/20 µs EFT pulse. This rating ensures that the varistor can handle the vast majority of voltage surges it may encounter. The V250LA10 is also capable of dissipating a maximum of 3.14 watt when in an overload condition. This allows the varistor to absorb excess energy before it can cause any damage to the connected components.

In summary, the V250LA10 is a popular metal oxide varistor manufactured by Bourns, Inc. It is specially designed to provide overvoltage protection for automotive, consumer, and industrial applications. The V250LA10 has a 250 V Maximum Working Voltage rating and has a maximum surge current of 10 kA 8/20 µs EFT pulse. It is also capable of dissipating a maximum of 3.14 watt when in an overload condition. All these features make the V250LA10 an ideal choice for protecting against voltage surges.
