Our varistors from Bourns
Multilayer Varistors (MLV) Bourns®
Multilayer varistors consist of many layers of MOVs stacked on top of each other. They inherently provide a matched voltage. An MLV is usually offered in a size 2220 package. With an Imax of 2 kA, an MLV can easily outperform a single layer MOV in a 4032 package that is twice the size (Imax rating = 1200 A). Due to their small size, most MLVs are designed for low voltages, usually below 200 V at 1 mA.

Metal Oxide Varistors (MOV) Bourns®
Metal oxide varistors (MOVs) are bi-directional and non-linear surge protection devices used in a variety of applications to limit voltage during an overvoltage or transient event. These highly reliable and robust surge protection devices are available in various form factors and surge protection ranges. An MOV is a non-linear device, which means that its characteristics do not change gradually but suddenly when the voltage reaches or exceeds its parameters. An MOV also has non-resistive current-voltage characteristics similar to those of a diode. However, unlike a diode, an MOV has the same characteristics for both directions of the current flowing through it.

Varistors
Standard and customized varistors
Varistors are essential components in the field of surge protection that are used in various electronic applications. There are two main types of varistors on the market: metal oxide varistors (MOV) and multilayer varistors. Metal oxide varistors are particularly popular for their ability to absorb high transient voltage peaks, making them ideal for protecting household appliances and industrial equipment.
Multilayer varistors, on the other hand, are predestined for use in mobile devices and other miniature applications due to their compact design and excellent performance at lower voltages. In addition to the standard products offered, manufacturers and distributors also offer customized solutions to meet specific requirements in terms of voltage levels, energy capacity and form factors.
