Voltage Surge Protection Drives Growth in Chip MOV Market

 

The global chip metal oxide varistor (MOV) market was valued at US$ 82.2 Mn in 2022 and is projected to reach US$ 116.5 Mn by 2031, expanding at a CAGR of 3.9% during the forecast period from 2023 to 2031. MOVs, vital for protecting sensitive electronic circuits against voltage surges and transients, are witnessing increased adoption due to the rise in compact and smart electronic devices, alongside booming automotive electronics.

Chip MOVs have become indispensable in modern electronics for their ability to manage transient voltage threats in compact form factors. The automotive industry, in particular, is accelerating the demand for MOVs due to their robust surge protection in critical components like ECUs and infotainment systems. The shift towards electric vehicles (EVs) and autonomous driving systems is expected to further fuel this demand.

 

Market Drivers & Trends

One of the primary market drivers is the growing need for circuit protection across miniaturized and sensitive electronic systems. As devices become smaller and more complex, they also become more vulnerable to voltage surges from lightning strikes, electrostatic discharge (ESD), or power fluctuations. Chip MOVs offer a cost-effective and reliable means of protecting these components, especially in consumer electronics, automotive systems, and industrial equipment.

Another key trend is the development of SMD multilayer MOVs. These compact, surface-mountable varistors feature multiple alternating layers of metal electrodes and zinc oxide ceramics. This multilayer construction improves performance characteristics such as energy absorption, transient suppression, and response time. Their growing use in IoT devices, smartphones, laptops, and wearables supports the upward trajectory of the market.
