ERZ-E11E561 is a three-layer shielded Varistor from Littelfuse. This Varistor is commonly used in several applications ranging from automotive to industrial to consumer products. The Varistor can be used for EMI/RFI attenuation, as well as overvoltage protection and surge suppression.

Varistors like ERZ-E11E561 are devices that use electrolytic capacitors to provide overvoltage protection or surge suppression. When the Varistor is subjected to an overvoltage, the components of the Varistor react by increasing the resistance and limiting the current that can flow through it. This helps protect any connected equipment from the harmful effects of an excessive voltage or surge current.

ERZ-E11E561 is a non-linear three-layer shielded Varistor for EMI/RFI attenuation in various industrial and commercial applications. The Varistor consists of three layers that consist of a non-linear, high-conductivity, carbon composition layer, a semi-conductive layer and an outer shield against electrical interference, providing the Varistor with the durability and reliability necessary for modern applications.

The operating principle of the ERZ-E11E561 is relatively simple. When subjected to an overvoltage, the electrolytic component of the Varistor increases its resistance, by trapping and blocking the excess voltage. This helps protect any connected equipment from the harmful effects of an excessive voltage or surge current.

The ERZ-E11E561 is used in a variety of applications, such as automotive, industrial, and consumer products. In automotive applications, the Varistor is mostly used to protect electronics from overvoltage surges. The Varistor can also be used in industrial applications such as protection of fluorescent lighting in commercial buildings. In consumer products, the Varistor provides overvoltage protection and surge suppression for high-end home entertainment systems.

ERZ-E11E561 is just one example of a Varistor, but it is a very versatile and reliable device that is suitable for a vast range of applications. It is a cost-effective solution that provides great results in a variety of scenarios, giving the user peace of mind that their equipment and devices are well protected.
