Inductor Market - A Brief Overview

By Knowledge Sourcing Intelligence Thought Articles

An inductor is also known as a coil, choke, or reactor that is a passive two-terminal electrical component. It stores energy in a magnetic field when an electric current passes through it. The use of inductors for varied end-use industrial applications holds importance in driving the market growth.

Inductors deal with current and voltage where it is used for measuring change in current on the basis of voltage applied to it. The current increases when the voltage is laid across the inductor. Inductors react in a different manner to the alternating and direct current, AC and DC.

Inductors are used in different applications ranging from electronics to broad application areas that include noise elimination, voltage stabilization, power electronic equipments and automobile operations among others. According to the need of a specific industry vertical, inductors are available in different sizes and ratings. Also, they are of different types including coupled inductors, multi-layer inductors, molded inductors, power inductors, ceramic core inductors, and chokes. Different applications include their use in tuning circuits, utilization as sensors, inductors are utilized for energy storage in a device, they are utilized in induction motors, used as transformers, utilized as filters, and are also used as ferrite beads. The growing adoption of mobile devices round the world are contributing to surging the inductor market growth. This is mainly due to the fact that inductors in the form of ferrite beads are used in the most popular electronic devices such as laptops, mobile phones, TV tuners, and gaming systems. These are used for minimizing interference and ensuring signal integrity.

The medical device industry is dependent on the other industries where the country holds a competitive advantage. These comprise microelectronics, telecommunications, instrumentations, and software development. Significant collaborations resulting in recent technological innovations has further bolstered the medical device market growth, further strengthening the inductor market growth in the United States along with the other regions of the world. Additionally, with the growing geriatric population along with the growing number of chronic diseases, the demand for effective medical devices will continue to soar, further putting a positive impact on market growth as well.

Product launches by the companies indicating innovations taking place at significant pace are further contributing to propelling the market growth. In 2019, KEMET Corporation announced the launch of a novel range of SMD metal composite power inductors. The devices in the new product line are capable of developing more efficient DC to DC switching power supplies and other applications related to power that include EMI filtering.

In 2019, TDK Corporation announced the expansion of its line-up of metal core power inductors with the launch of novel SPM-VT series. These are designed specifically for meeting high thermal and current demand of automotive LED headlights. The product features include a wide operating temperature range between -55°C to +155 °C. The current ranges from 4.7 A to 36.6 A. The new components are currently available in three sizes. The inductance range is between 1 µH to 47 µH. The mass production is projected to start from September 2019.

In 2020, Coilcraft Inc. announced the launch of the three power inductors used for automotive and other harsh-environment applications. The high-performance molded power inductors provide operating voltage ratings of 120 volts, that is 50% higher in comparison to standards versions. These also offer low DC resistance and low AC losses for power converter efficiency at high ripple current and high frequencies. The inductors feature a rugged and composite construction that offer magnetic shielding and minimize audible buzzing. XEL401xV series are available in six inductance values ranging from 92 nanohenries to 780 nanohenries, with current rating to 24 A. XEL4020V series are available in 10 values ranging from 0.08 microhenries to 2.2 microhenries. The current ratings to 33.2 A. On the other hand, XEL4030V series are available in 13 values ranging from 0.10 microhenries to 6.8 microhenries, with current ratings to 30 A.

Furthermore, inductors are used for various mission critical defense and aerospace applications. The AE425P JB series of low-profile inductors from the Coilcraft-CPS company is made in accordance with the NASA low outgassing specifications. The power inductors are 1.8 mm high with a footprint of 3.9 mm2. The suspended core construction allows to pass vibration testing and shock testing to 80G and 1000 G. This feature has made it an ideal solution for a variety of mission critical applications in military and aerospace sectors. The use of high temperature materials has allowed the operation to be carried out in ambient temperatures up to 155 °C. For best possible board adhesion, the power inductor features tin-lead termination.
