Market Trends of Global Inductors Industry
Frequency Inductor Expected to Witness Significant Growth
- Frequency inductors, called RF (radio frequency) inductors, are specifically designed for applications in high-frequency circuits, such as those used in radio communication, wireless technology, and radar systems. They are necessary because regular inductors, intended for low-frequency applications, may not perform well or even malfunction at higher frequencies due to parasitic capacitance and skin effects. Frequency inductors are optimized to minimize these issues, allowing them to maintain their desired inductance and performance across a wide range of frequencies.
- RF inductors are mainly characterized by low current rating and high electrical resistance. However, the wire resistance increases as the high frequencies are used here. In addition, a few effects come into the picture because of these high-resonant radio frequencies. These include skin effect, proximity effect, and parasitic capacitance.
- RF inductors can be manufactured in different ways. For instance, Murata, one of the prominent vendors of inductors, uses wire wound manufacturing methods, film manufacturing methods, and multi-layer manufacturing methods. Each method has different characteristics.
- There has been a prevailing trend of miniaturization of RF inductors due to their usage in small communication products such as smartphones, wireless modules, Bluetooth modules, etc. Hence, the vendors in the market are focusing on developing small yet powerful RF inductors to contribute to the growth of mobile communication.
- As consumer electronics is the prominent driver for inductor demand, the growing push to adopt 5G technology is expected to drive the demand for various consumer electronics and communication devices worldwide, impacting market growth. The 5G deployments worldwide are increasing the need for RF inductors for IoTs and conventional smartphones. According to the 5G Americas Organization Report released in May 2023, 5G mobile subscriptions were expected to exceed 1.9 billion in 2023 and reach 5.9 billion by 2027.
- In February 2023, GSMA reported that 5G connections are anticipated to double over the upcoming two years. In addition, GSMA also reported that the growth would come from key markets within APAC and LATAM, like Brazil and India, which have recently launched 5G networks. The expansion of services from Airtel and Jio in 2023 was pivotal to India's ongoing adoption. Moreover, GSMA 5G is expected to account for 145 million in India by the end of 2025.

Asia-Pacific to Register Major Growth
- The Asia-Pacific inductor market is driven by demand from industrial economies and technologically advanced countries, such as China, Korea, Japan, and India. China is one of the largest sources of demand for inductor components, owing to the rapidly growing semiconductor industry and industrial automation.
- The growth of smartphones has been exponential, and the number of smartphone users in the Asian-Pacific countries has increased in the past few years. According to GSMA’s Mobile Economy report, Asia-Pacific is on its way to becoming the world’s largest 5G region by 2025, led by China, Japan, South Korea, and Australia, as well as commercial 5G network launches that are expected to reach 675 million 5G connections, more than half of the global 5G total scheduled by 2025.
- Automotive infotainment systems provide music, videos, other multimedia content, navigation, internet connectivity inside vehicles, and communication with outside systems. Vendors are offering new technology designed to reduce the weight of cable harnesses comprising various telecommunication buses. For instance, in January 2024, TDK Corporation introduced its latest inductor KLZ2012-A series (2.0 mm (L) x 1.25 mm (W) x 1.25 mm (H)) for automotive audio bus (A2B) applications with a wide operation range, high durability, and superior inductance tolerance.
- Ferrite core inductors are expected to witness a rise in adoption owing to the growth in the automotive sector to achieve high efficiency in power conversion models used in automotive. They are also helpful for transformers and inductors in automotive and electronic applications. Industry 4.0 has increased the automation of manufacturing and production processes, thus leading to an increased use of inductors, owing to their presence in many electronic assemblies.
- Overall, along with the rapidly growing automotive sector and increasing demand for inductors, countries such as China, Japan, and South Korea are leading various Smart city initiatives. These innovative initiatives in the region create the potential for using inductors across automotive, transportation, energy, and utilities. Furthermore, communication in the area has also witnessed considerable progress, with companies like Murata deploying specialized inductors for NFC circuits. Such developments are likely to propel the region’s market growth.
