Compared with the gradual slowdown in the growth of the mobile phone and tablet market, the growth force of the automotive electronics market continues to strengthen. In view of this, although the performance of the inductance manufacturer Kellexin in the mobile device market continues to be outstanding, for example, benefiting from the smart phone’s transition from 3G to the 4G era, the amount of inductors has increased greatly. Kellissin’s integrated choke ( Mini Molding Choke) and 0201 miniature high-frequency inductors are in short supply. However, in order to maintain a long-term growth trend, the company has actively cultivated the automotive electronics market. In recent years, it has also successively delivered specific layout results, which is expected to become the next wave of Qili The driving force of the growth peak.

The automotive electronics market can grow
The data speaks for words. According to a report by research and consulting agency Gartner, global tablet shipments reached 216 million units in 2014. According to a market research organization IDC research, global tablet shipments reached 229.3 million in 2013. Taiwan, an increase of 58.7% from 144.5 million in 2012. From these data, it is not difficult to see that the global tablet sales for the entire year of 2014 have significantly slowed down, and the global tablet shipment growth rate in 2015 will only be 8%. In contrast, automotive electronics is showing a booming situation. According to the research organization Strategy Analytics, the global automotive electronics output value will grow from 197.5 billion US dollars in 2013 to 238.8 billion US dollars in 2015.

In view of the infinite potential of the automotive electronics market, Kellett’s new product layout focuses on power inductors (Power Inductor) and integrated inductors (Molding Choke). In terms of power inductors, for the low DC resistance and high current requirements of automotive power systems, Kellett uses power inductors with magnetic shielding structures to meet customer needs. Kellett further explained that compared to traditional power inductors with a base structure, Kellett’s SLF (closed magnetic circuit) power inductor series uses no base design, so the cost can be reduced by 15%, and the resistance Value and other characteristics are even better than traditional solutions.

Compatible with new designs and conquer high-threshold markets
More importantly, Kellett’s automotive SLF power inductor design is fully compatible with the layout of Japanese suppliers that have dominated the market for a long time. In other words, automotive customers can modify the original circuit design without changing the original circuit design. And adopt the new SLF power inductor of Kellett. The senior executives of Kellett pointed out that compared with the 3C electronics market, the frequency of changes in automotive electronics related designs is extremely low, and the selection and replacement of suppliers requires long-term verification. Therefore, it is extremely difficult to enter the automotive market. However, under the strategy of being compatible with mainstream products and more price-competitive, Kellett has entered the high-threshold automotive market.

Similarly, for the Power Molding Choke used in the car’s START-STOP idling stop system, Kellett also adopted a different approach from the traditional design. Generally, Molding Choke uses Wired-pads, while Chilisin uses Lead-frame. The biggest advantage of this approach is that the performance in the vibration test is more outstanding, and the weldability and flatness are better, and it can pass the AEC-Q200 test smoothly. AEC-Q200 is a certification specification for stress testing of passive components for vehicles. Many of Kellett’s power inductor series and chip ferrite beads (Chip Ferrite Bead) have passed the AEC-Q200 test, which is fully in line with the automotive industry’s requirements for electronic components. The strict requirements.

In addition to the above products, Kellett also expects to further promote the UHEI (Ultra High Efficiency Inductor) series and MTFA 2-in-1 form of inductance array (Array) products to the automotive application field, providing high efficiency for automotive industry players And a variety of choices with good characteristics.

The proportion of contributions from the automotive market is gradually increasing
Compared with the requirements of 3C products for electronic parts, which focus on lightness, thinness and shortness, the requirements of the automotive industry focus on stability and whether they can adapt to harsh operating environment conditions, such as high temperature may be as high as 150 degrees Celsius, while Kellett’s new inductor products The reason why the company has both reliability and cost considerations is closely related to the company’s own powder factory and powder formulation ability. As a result of not fake foreign demands, Kellett can quickly adopt new materials, provide effective solutions in the first time, and quickly meet customer requirements for specifications and characteristics, and this is also one of the foundations for providing market-competitive prices.

The senior executives of Kellett said that Kellett is targeting several major automakers in Europe, Asia and the United States. It is expected that the contribution from the automotive electronics market will account for the company’s overall turnover, which will increase from 3% in 2014 to 5% this year. The increase is not large, but it also shows that Kellett’s layout in the auto market has gradually paid off.”
