Market Dynamics and Key Growth Drivers
The automotive multilayer varistor market is experiencing a surge in growth due to multiple factors:
- Rising Electronics Integration in Vehicles:
Today’s vehicles contain up to 100 electronic control units (ECUs), handling everything from safety features to entertainment systems. These components are susceptible to overvoltage and require robust protection, making varistors indispensable. - Accelerated EV Adoption:
Electric vehicles (EVs) feature more power electronics than traditional internal combustion engine (ICE) vehicles. From battery management systems to inverter circuits and charging infrastructure, MLVs play a pivotal role in safeguarding sensitive components. - Miniaturization and Higher Voltage Requirements:
As demand grows for compact automotive designs, varistors are required to be smaller while still offering high energy-handling capabilities and a wide range of operating voltages. - Regulatory Push for Safety and Reliability:
Compliance with international automotive standards such as AEC-Q200 and ISO 26262 for functional safety is pushing OEMs to use high-quality protection components like multilayer varistors.
