TDK Corporation (TSE:6762) launches the ADL8030VA, a high-performance inductor designed specifically for power-over-coaxial (PoC) applications. Due to its high impedance over a wide frequency range, this component streamlines the PoC filter design by requiring only one single component instead of the conventional approach with two or more inductors. This significantly reduces complexity and cost in advanced driver-assistance systems (ADAS) and other automotive electronics, where space efficiency and reliability are critical. With the ADL8030VA, TDK is once again driving mobility transformation toward a more connected and safe future.

TDK Corporation (TSE:6762) announces the HVC50, a high-voltage DC contactor designed for connecting or disconnecting lithium-ion batteries with up to 1500 V in traction applications, energy storage systems (ESS), and megawatt charging systems (MCS). With this component, TDK enables its customers to drive the green transformation towards an all-electric society and reduce carbon footprint.

Since the advent of large language models (LLMs), artificial intelligence (AI) has been utilized in various scenarios, making AI a familiar presence.
The infrastructure technology supporting this AI utilization is a hardware system capable of advanced and large-scale parallel computation, known as AI accelerators. Currently, many AI accelerators are installed in data centers, but the server/storage/network systems traditionally used in data centers are not designed specifically for the operation of AI accelerators.
Therefore, to install AI accelerators in data centers and provide services that meet the demand for AI, many technical challenges need to be addressed. Among these, cooling of the equipment is considered the most critical issue, and the development of next-generation cooling methods for AI accelerator systems is underway. Among these, immersion cooling systems are said to be the most promising technology due to their significant cooling effects.
This article introduces our company's efforts regarding passive component products for AI accelerator systems using this immersion cooling method.

The development of next-generation vehicles for fully automated driving is gaining momentum, and the architecture of in-vehicle networks is beginning to undergo major changes.
In-vehicle Ethernet is attracting attention in automotive networks, and interfaces such as 100BASE-T1 (100Mbps) and 1000BASE-T1 (1Gbps), whose specifications are defined by the OPEN Alliance, are becoming popular. Recently, a new 10BASE-T1S (10 Mbps) has been added to this in-vehicle Ethernet, attracting a great deal of attention because of its ability to provide multi-drop connections.
This article introduces common-mode chokes and chip varistors that comply with OPEN Alliance specifications at the right time.

The advancement of digital technologies, such as the integration of AI capabilities and the enhancement of display and camera resolutions, has led to a continuous increase in the volume of data handled by digital devices like laptops and smartphones. This has driven the need for faster and higher-capacity signal transmission. However, the noise generated by these devices is also shifting to higher frequencies, necessitating countermeasures to mitigate interference with other devices and prevent signal degradation.

The TCM06U series, a compact common mode filter, is introduced as an optimal solution for noise suppression in high-speed differential signaling.

TDK has recently expanded its lineup of 3-terminal feedthrough filters, known as the "YFF Series."
With advancements in automotive electronic systems aimed at enhancing safety, comfort, and infotainment capabilities, there is an increasing demand for measures to prevent system malfunctions.
To suppress voltage variation and high-frequency noise, which can cause such malfunctions, numerous capacitors are typically employed. However, the trend toward miniaturization of these systems raises concerns about mounting space limitations due to the increased number of components.
To address these challenges, 3-terminal feedthrough filters, characterized by low ESL (Equivalent Series Inductance), are gaining significant demand. Their high noise suppression effectiveness is expected to reduce the number of components and improve performance characteristics.

PFAS, known as “forever chemicals,” pose significant environmental and health challenges due to their persistence in ecosystems and resistance to conventional treatment methods.
At SUIKI, we are pioneering the development of innovative solutions to address these challenges, starting with our prototype, Aquahive.

This article highlights the urgent need for PFAS destruction, the advantages of electrochemical oxidation (ECO), and the promising capabilities of our prototype.

TDK Corporation (TSE:6762) launches B58101A0851A000, the first in a new line of immersion temperature sensors (ITS), designed specifically for EV powertrain cooling applications. This highly responsive, fully sealed NTC thermistor is engineered to provide fast and precise temperature control, e.g., for oil-cooled systems. Oil cooling is anticipated to become the dominant temperature management method in the electric drivetrain of EVs. Leveraging TDK's expertise in developing tailored temperature sensor solutions, the ITS offers a flexible, customizable design adaptable to various installation positions, cooling fluids, and mounting configurations.

With the increasing adoption of renewable energy and the proliferation of EV fast-charging stations, the demand for high-power power supplies is growing.
Transformers used in these power supplies are expected to be more compact, efficient, and generate less heat. Ferrite materials are integral to transformer products. However, core losses (iron losses) in ferrite cores can vary significantly depending on the core size, operating frequency, and load. Therefore, selecting the optimal ferrite material is a crucial aspect of transformer design.
This article introduces the features of the PEL95 material, developed specifically for high-power applications, and key considerations for its use.
