LG Innotek Unveils Ferrite Materials for Ultra-Thin Power Components
Published2020.10.14 14:5560% thinner than products equipped with general power modules
10% less volume and weight, and 20% lower temperature
With the growing demand for ultra-small, high-performance electronic components, ferrite is attracting attention as a next-generation material. Ferrite is a magnetic material primarily composed of iron oxide. Ferrite powder is solidified into tiles. It is primarily used to change voltage or remove unwanted signals generated by current fluctuations.
LG Innotek announced on the 14th that it has successfully developed a ferrite with low power loss and high efficiency. This ferrite reduces heat-related power loss by up to 40% compared to conventional ferrite. Furthermore, it maintains its low-loss characteristics at temperatures ranging from -40°C to 140°C, ensuring quality even in high-temperature TV interiors and diverse vehicle driving environments.
This material allows TV power modules to be as thin as 9.9mm, reducing TV thickness by approximately 60%. While a 65-inch OLED TV equipped with a standard power module is approximately 46.9mm thick, a TV equipped with LG Innotek's high-efficiency ferrite-based power module is less than 20mm thick. This is because the number of parts required to secure the required power is reduced by 1/3 due to less power loss, and the thickness of the parts is 40% thinner than before.
Applying this material to automotive DC-DC converters can reduce the converter's volume and weight by approximately 10% compared to conventional converters and increase its energy efficiency by up to 1.2 percentage points. Another advantage is that it can reduce the risk of fire caused by overheating in vehicles. Due to its low heat generation, this material can lower component temperatures by up to 20°C compared to conventional converters.
An LG Innotek official stated, "We are promoting our high-efficiency ferrite material to global electronics companies and automakers, aiming for mass production in the first half of next year." They added, "Based on our approximately 120 related patents, we are focusing on R&D to further enhance performance." They also emphasized, "Our ferrite material is cheaper and offers greater supply stability than products from Japanese companies, which currently dominate the ferrite market."

LS Cable & System commercializes cables using carbon fiber as a shielding material.
Carbon fiber weighs only one-quarter that of steel while offering 10 times the strength and 7 times the elasticity. When carbon fiber is applied, cable weight is reduced by 10–20% or more, and flexibility and durability are improved by 30% or greater. Accordingly, LS Cable announced that it has commercialized telecommunications cables incorporating carbon fiber. Previously, copper or aluminum has been used as shielding material to protect cables.

Material and structural innovation, development of ultra-high sensitivity microwave detectors
Professor Lee Gil-ho's team from the Department of Physics at POSTECH has jointly developed with Harvard University, MIT, Raytheon BBN and others an ultra-sensitive detector capable of detecting microwave intensity at the theoretical limit of approximately 1 attoWatt (aW; 1 aW = 10⁻¹⁸ W) based on a one-second measurement standard. Recently, as microwave has become known to be applicable to quantum information technology such as quantum computing and quantum information communication, research aimed at detecting with ultra-high sensitivity is being actively conducted.

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
