The multilayer varistor market is poised for significant expansion due to multiple converging trends—widespread adoption of electric vehicles (EVs), the proliferation of smart grids, increased penetration of Internet of Things (IoT) devices, and accelerating 5G deployment. Multilayer varistors, being compact, efficient, and capable of protecting delicate circuitry from voltage surges, are indispensable in these high-tech environments.
Asia-Pacific, particularly East Asia, remains the manufacturing and innovation hub for MLVs, thanks to a strong industrial base in China, Taiwan, and Japan. However, markets in Europe and North America are also gaining traction, driven by stringent EMC standards and rapid expansion of EV and renewable energy infrastructure.
Market Overview
Multilayer varistors are vital electroceramic components made from alternating layers of metal oxide and ceramic materials, primarily zinc oxide. These layers provide non-linear voltage-current characteristics, enabling them to absorb excessive transient voltages. The result is superior protection for sensitive electronic devices against electrostatic discharge (ESD), electrical overstress (EOS), and lightning-induced surges.
Their compact design, low leakage current, and high surge energy absorption make them ideal for consumer electronics, automotive systems, medical devices, industrial machinery, and telecommunication infrastructure.
Market Drivers
- Boom in Consumer Electronics
The rising global appetite for AI-powered electronics—including smartphones, smart TVs, and wearables—has created unprecedented demand for compact, high-performance protection components. India, for example, is poised to hit US$ 300 Bn in electronics output by 2025–26, according to the Ministry of Electronics and Information Technology (MeitY). Taiwan, another major player, reported a 11.2% rise in export orders for electronics in October 2024, touching US$ 55.4 Bn.
These trends underscore the critical need for MLVs in protecting AI-enabled, high-frequency electronic circuits from transient electrical threats, ensuring consistent performance and durability.
- Telecommunications Infrastructure Expansion
Next-gen telecom technologies like 5G require precision-engineered electronics capable of high data throughput. MLVs are essential here, safeguarding base stations, networking hardware, and power distribution units. Government investments in digital infrastructure globally are reinforcing this demand:
- India announced a ₹26,316 crore investment for expanding 4G connectivity to 6,279 rural villages.
- Australia committed US$ 3.8 Bn to upgrade the NBN, including laying 23,000 km of fiber-optic cable.
As digital connectivity deepens across the globe, MLVs will continue to be integrated into critical telecommunication equipment.
