Varistors, also known as voltage-dependent resistors (VDRs), are one of the most important protection technologies used in a variety of electrical and electronic systems.They are designed to provide robust protection against overvoltage transients, ensuring that expensive and vulnerable system components are not damaged by excessive voltage levels.
The V12ZC1PX2855 is an industry-leading varistor fromKnowles Capacitors, specifically designed to protect the sensitive circuitry and components ofelectronic systems from electrostatic discharge (ESD) and other transient, high-energy surge events.This high-performance component is constructed from zinc oxide ceramic cores, which provide exceptional temperature stability and surge current carrying capacity.

This varistor is able to function within an operating temperature range of -55˚C to 125˚C, so is suitable for use in both indoor and outdoor applications.The V12ZC1PX2855 also has a wide capacitance range from 7pF to 120pF with an ESD clamping voltage range of 6 volt to 27 volts.The device is also capable of operating continuous operating AC voltage of up to 300V and peak operating voltage of 450V, and withstanding contact discharge of 8kV. It is typically used in automotive applications, industrial control systems, telecommunications systems, and consumer electronics.

The working principle of the V12ZC1PX2855 is relatively straightforward and is based on the highly non-linear ZnO dielectric material used for its construction.Under normal operating conditions, the component acts an open circuit, with voltage and current flow passing through unimpeded.When a transient voltage surge or ESD event occurs, however, the ZnO material creates a short across the varistor, effectively clamping the voltage to a safe level.This prevents any damage occurring to the sensitive electronics due to excess voltage.

The V12ZC1PX2855 is thus an invaluable component for providing protection from overvoltage and ESD events.Its robust construction and wide range of capacitance and voltage ratings makes it suitable for a wide range of applications, and its reliable performance enables system designers to maintain the highest level of safety for their electronics.

Knowles’ V12ZC1PX2855 is a high-performance varistor that has been extensively tested to ensure maximum reliability under real-world conditions. Its reliable protection performance has ensured that it has become the industry-standard for voltage surge and electrostatic protection systems across a wide range of applications.
