Delta Electronics Inc (台達電), the nation’s top supplier of power supply units, yesterday said it plans to build 30 more hot press choke assembly lines next year to meet rising demand for the energy-saving mobile device component from smartphone makers, including Apple Inc.
Delta currently supplies up to 300 million hot press choke units a month at a 90 percent yield rate.
Delta said it aims to optimize existing assembly lines first, before expanding capacity to double its hot press choke shipments to 600 million units a month later next year.
“There is a strong likelihood that demand for hot press chokes will increase because the mobile device component can boost the power efficiency of new mobile devices,” Delta spokesperson Jesse Chou (周志宏) told an investors’ conference in Taipei.
In the lately emerged hot press choke market, Delta is able to outperform its Japanese rivals such as Murata Manufacturing Co Ltd and TDK Corp because the company has a strong engineering team that focuses on research and development of power-efficient passive components, Delta chairman Yancey Hai (海英俊) said at the conference.
Hai said Delta’s in-house R&D department is now capable of designing customized hot press choke products, conducting product tests and mass-manufacturing the product within three months.
“With expanded capacity [after new assembly lines are built], Delta is going to ship considerably more hot press chokes next year, continuing its leadership in the market,” Hai said.
Unlike traditional power chokes, which are designed to block higher-frequency alternating current while allowing lower-frequency current to pass in an electrical circuit, hot press chokes are smaller and have higher performance, Chou said.
The hot press choke sector remains a “seller’s market” as there are still few power supply unit makers in the market, while demand for energy-efficient mobile device components continues to expand, he said.
Currently, Delta supplies hot press chokes for high-end smartphone models such as Apple Inc’s iPhone 5s, the company said.
Due to increased shipments of passive components, Delta saw its net profits grow 5 percent quarter-on-quarter to NT$4.53 billion (US$154.05 million) in the last quarter, with earnings per share of NT$1.86.
The figure, however, reflects a 6 percent year-on-year contraction because of decreased shipments of power supplies used in traditional desktops and laptops, the company said.
Despite a better product mix, total sales this quarter were expected to decline from NT$46.1 billion last quarter due to seasonal factors and macroeconomic uncertainties in China, Delta said.
Driven by growing demand for consumer electronics ahead of year-end holidays, Delta forecast its fourth-quarter sales of hot press chokes and other passive components would achieve quarter-on-quarter growth.
Total sales of passive components were estimated to account for 15 percent of the company’s total sales this quarter, up from a 10 percent stake last quarter, the company said.
To increase sales sources in response to weakening demand for traditional PCs, Delta aims to develop more power supply units designed for large-sized data centers, as well as those used in electric cars, Hai said.
Hai said Delta has been in talks with foreign clients about building a smart grid in the US to offer stable power supply to electric car owners in the country.
Delta’s shares closed up 3.33 percent at NT$155 yesterday, outperforming the benchmark TAIEX, which gained 0.73 percent.
OpenAI has warned US lawmakers that its Chinese rival DeepSeek (深度求索) is using unfair and increasingly sophisticated methods to extract results from leading US artificial intelligence (AI) models to train the next generation of its breakthrough R1 chatbot, a memo reviewed by Bloomberg News showed. In the memo, sent on Thursday to the US House of Representatives Select Committee on China, OpenAI said that DeepSeek had used so-called distillation techniques as part of “ongoing efforts to free-ride on the capabilities developed by OpenAI and other US frontier labs.” The company said it had detected “new, obfuscated methods” designed to evade OpenAI’s defenses
NEW IMPORTS: Car dealer PG Union Corp said it would consider introducing US-made models such as the Jeep Grand Cherokee and Stellantis’ RAM 1500 to Taiwan Tesla Taiwan yesterday said that it does not plan to cut its car prices in the wake of Washington and Taipei signing the Agreement on Reciprocal Trade on Thursday to eliminate tariffs on US-made cars. On the other hand, Mercedes-Benz Taiwan said it is planning to lower the price of its five models imported from the US after the zero tariff comes into effect. Tesla in a statement said it has no plan to adjust the prices of the US-made Model 3, Model S and Model X as tariffs are not the only factor the automaker uses to determine pricing policies. Tesla said
China’s top chipmaker has warned that breakaway spending on artificial intelligence (AI) chips is bringing forward years of future demand, raising the risk that some data centers could sit idle. “Companies would love to build 10 years’ worth of data center capacity within one or two years,” Semiconductor Manufacturing International Corp (SMIC, 中芯) cochief executive officer Zhao Haijun (趙海軍) said yesterday on a call with analysts. “As for what exactly these data centers will do, that hasn’t been fully thought through.” Moody’s Ratings projects that AI-related infrastructure investment would exceed US$3 trillion over the next five years, as developers pour eye-watering sums
Australian singer Kylie Minogue says “nothing compares” to performing live, but becoming an international wine magnate in under six years has been quite a thrill for the Spinning Around star. Minogue launched her first own-label wine in 2020 in partnership with celebrity drinks expert Paul Schaafsma, starting with a basic rose but quickly expanding to include sparkling, no-alcohol and premium rose offerings. The actress and singer has since wracked up sales of around 25 million bottles, with her carefully branded products pitched at low-to mid-range prices in dozens of countries. Britain, Australia and the United States are the biggest markets. “Nothing compares to performing
