Varistor Products

Bourns provides a complete range of varistor technologies, form factors, and ratings to meet a wide range of voltage protection requirements in practically any application.

The first is the SMD, which is a traditional MOV devices offered in a surface-mount package. This is used to protect electronic equipment from high voltage surges; MLVs provide excellent on-board ESD and surge protection for consumer and vehicle electronics; automotive varistors for usage in severe environments such as those found in automotive and industrial applications; hybrid varistor are created by combining different varistor technologies for increased performance and space savings; through-hole MOVs are conventional PCB components that offers tough protection in an industry-standard form. Protected equipment may live in surroundings with the most severe disturbances due to high energy varistors.

Our product portfolio provides designers with the tools they need to address the complex technology requirements of a wide range of applications, including low voltage board level (LVBL), telecommunication, automotive electronics, AC-line, TVSS, and high-energy industrial equipment designs.
