Data Triangulation
Once the overall size of the varistor and GDT market was determined using the methods described above, it was divided into multiple segments and subsegments. Market engineering was performed for each segment and subsegment using market breakdown and data triangulation methods, as applicable, to obtain accurate statistics. Various factors and trends from the demand and supply sides were studied to triangulate the data. The market was validated using both the top-down and bottom-up approaches.
Market Definition
The varistor and gas discharge tube (GDT) market encompasses components designed to protect electronic circuits and systems from voltage surges and transient events. Varistors, primarily metal oxide varistors (MOVs), offer voltage-dependent resistance that clamps excess voltage to prevent circuit damage, while GDTs provide high-energy surge protection by conducting large currents to the ground when a specific breakdown voltage is exceeded. These components are essential in applications such as consumer electronics, telecommunications, industrial equipment, automotive systems, and power distribution networks, where reliable protection against overvoltage, lightning strikes, and electrostatic discharge (ESD) is critical to ensuring device longevity and safety.
The report comprehensively analyzes the varistor and GDT market based on product type, application, and region. A few key manufacturers of varistors and GDTs are Littelfuse, Inc.
