Working Principle

The B72220S2421K101 Varistor works on the principle of temperature-based differential voltage. It uses a unique thermistor based process that allows the voltage rating to vary approximately with the temperature of the component. The thermistor typically absorbs heat generated by the power dissipation within the component and converts that heat into increased electrical resistance. This resistance causes a decrease in the voltage rating of the Varistor, thus providing increased protection for related components.

The B72220S2421K101 Varistor is designed to handle up to 25kA of transient voltage, provide 1200V of protection and operate in temperatures up to 125C. It is also designed to handle short surge pulses up to 6.2kV and has a range of 10nF to 30nF. It is made from high quality and reliable components that ensure optimum performance and reliability.

In general, the B72220S2421K101 Varistor is used to provide high power dissipation, excellent transient voltage protection, and low operating temperatures, making it an ideal solution for applications that require high levels of protection.
