TAIYO YUDEN Commercializes the HVX (-K) and HTX (-K) Series of Conductive Polymer Hybrid Aluminum Electrolytic Capacitors Capable of Handling Large Currents and High Voltages

Published

on

TOKYO, July 1, 2026 /PRNewswire/ — TAIYO YUDEN CO., LTD. (Representative Director, President and CEO: Katsuya Sase; Head Office: Chuo-ku, Tokyo) has commercialized the new HVX (-K) and HTX (-K) series of conductive polymer hybrid aluminum electrolytic capacitors (hereinafter referred to as hybrid capacitors) that comply with the AEC-Q200 (Note 1) Stress Test Qualification for Passive Components.

These hybrid capacitors are intended for noise suppression and power smoothing in power supply circuits for control functions such as automotive power steering or safety functions such as ADAS.

The new hybrid capacitors offer significantly improved capacitance characteristics over our earlier HVX and HTX series. TAIYO YUDEN have commercialized 46 types of hybrid capacitor, including the 80 V rated type RAHTX181M1RGP5005K (φ12.5 x 16.5 mm; rated ripple current: 3,900 mArms@135°C), with a lineup of seven sizes ranging from φ6.3 x 7.7 mm to φ12.5 x 16.5 mm.

In June 2026, mass production began at the Shirakawa Plant (Nishi-Shirakawa-gun, Fukushima Prefecture) and Aomori Plant (Kuroishi City, Aomori Prefecture) of our subsidiary, ELNA CO., LTD. (President: Masahiro Kohsaka; Head Office: Chuo-ku, Tokyo). Samples are available for 150 yen per unit.

Technology Background
Hybrid capacitors use a conductive polymer and an electrolyte solution as the electrolyte. This composition takes advantage of the low ESR characteristic of conductive polymers and the self-repairing property of anodic oxide film, which is a characteristic of aluminum electrolytic capacitors, achieving both high performance and reliability.

In recent years, the power supply voltage for automotive power circuits has increasingly been set to 48 V to improve power efficiency. Therefore, there is demand for hybrid capacitors capable of handling high voltages and large currents. Furthermore, as the number of power supply circuits required for electronic control systems such as ADAS, and vehicles with electrified powertrains such as EVs, continues to increase, more hybrid capacitors are being used for noise suppression and power smoothing.

To meet this requirement, TAIYO YUDEN has pursued the optimal design for all constituent materials used in its hybrid capacitors and commercialized the HVX (-K) and HTX (-K) series, which can achieve a rated voltage of 80 V at an upper limit of the operating temperature range of 135°C.

TAIYO YUDEN focuses on the development of products that meet market needs, and will continue to expand its hybrid capacitor lineup.

Dnotitia Unveils STAR-KV, Achieving UP to 20x KV Cache Compression, Selected as an ICML 2026 Spotlight Paper

Published

on

By

Introduces a low-rank-based approach to KV cache compression, one of the key bottlenecks in long-context AISpeeds up attention computation by up to 6.9x and overall generation throughput by up to 3.1x, moving beyond memory savings to faster inferenceSelected as a Spotlight paper at ICML 2026, representing about 2.2% of reviewed submissions and about 8.4% of accepted papersFollowing the attention around Google’s TurboQuant at ICLR 2026, STAR-KV presents another approach to advancing KV cache compressionPaper available on arXiv; source code released on GitHub

SEOUL, South Korea, July 1, 2026 /PRNewswire/ — Dnotitia Inc. (Dnotitia), a company specializing in long-term memory AI and semiconductor-based AI infrastructure technologies, has released the paper and source code for “STAR-KV: Low-Rank KV Cache Compression via Soft Thresholding for Adaptive Rank Control.” The technology was developed through a joint research effort involving UC San Diego’s VVIP Lab and Dnotitia researchers, and the paper was selected as a Spotlight paper at ICML 2026 (International Conference on Machine Learning 2026), one of the world’s leading conferences in machine learning.

In the experiments reported in the paper, low-rank compression alone reduced the KV cache by up to 75%. Combined with the mixed-precision quantization method proposed in the paper, STAR-KV compressed the full KV cache by up to 20x. The technology also improves computation speed through custom GPU kernels, increasing attention computation speed by up to 6.9x and overall generation throughput by up to 3.1x. STAR-KV also showed higher accuracy than major existing KV cache compression methods.

KV cache compression has become a key technical challenge in AI infrastructure. As research into reducing the memory bottleneck of long-context AI gains momentum, including the attention around Google’s TurboQuant at ICLR 2026, STAR-KV presents a new approach that combines low-rank compression with quantization and GPU execution optimization.

The KV cache is temporary memory stored on the GPU so that a large language model (LLM) does not have to recompute context it has already processed. As AI evolves into agentic systems that use multiple documents, conversation history, code, search results, and outputs from external tools, the amount of context a model must process is growing rapidly. In this environment, the KV cache has emerged as a key bottleneck affecting both GPU memory usage and inference cost.

According to the STAR-KV paper, when a LLaMA-3.1-8B model processes a 128K-token context at a batch size of 4, the KV cache accounts for about 81% of total GPU memory. As long-context AI becomes more widely used, KV cache compression is increasingly viewed as a core AI infrastructure technology for processing long context at lower cost.

ICML, where the STAR-KV paper was accepted, is widely regarded as one of the top international conferences in AI and machine learning, alongside NeurIPS and ICLR. ICML 2026 will be held from July 6 to 11 at COEX in Seoul. This year, 23,918 papers entered review, 6,352 were accepted, and 536 were selected as Spotlight papers. Spotlight papers account for about 2.2% of all reviewed submissions and about 8.4% of accepted papers.

Going forward, Dnotitia plans to further advance STAR-KV for use in real-world AI service environments and explore its application to open-source LLM inference frameworks such as vLLM.

“Technologies that help AI process longer context faster and at lower cost are advancing rapidly” said MK Chung, CEO of Dnotitia. “STAR-KV addresses the core bottlenecks in KV cache capacity and attention processing speed, and Dnotitia aims to contribute to the AI inference ecosystem through open sourcing.”

Co-inventor of early blockchain will guide SafeBets’ standards for verified identity, transparency, and public auditability

NEW YORK, July 1, 2026 /PRNewswire/ — SafeBets, the zero-wager prediction platform where users Win Without Risk, today announced that W. Scott Stornetta, CEO of SureMark Digital and a founding father of blockchain, has joined the company as Chair of its Advisory Council.

In 1991, Stornetta and his collaborator Stuart Haber published “How to Time-Stamp a Digital Document,” introducing cryptographic methods for linking and verifying digital records that would become cornerstones of blockchain technology. Their research is widely cited throughout the Bitcoin white paper as its data integrity foundation.

In the decades since, Stornetta and Haber have continued to advance the science of digital trust, from pioneering the first commercial digital time-stamping service to their current work on native digital identity. He is the Chief Executive Officer of SureMark Digital, with Dr. Haber serving as Chief Cryptographic Officer. As deepfakes and AI-generated impersonation erode confidence in digital communication, SureMark enables individuals and organizations to prove their identity, certify the authorship of their content, and refute forgeries, making authenticity verifiable at a time when seeing is no longer believing.

As Chair of the SafeBets Advisory Council, Stornetta will advise on the platform’s standards for verified identity, record-keeping, transparency, and public auditability.

SafeBets is built on a simple principle: the credibility of a prediction depends on trust in who made it. Participants forecast outcomes across crypto, commodity, stock, and currency markets, and the platform harnesses Collective Intelligence to surface the most accurate predictors. Stornetta’s leadership reinforces the company’s commitment to verifiable, tamper-evident prediction and positions SafeBets at the forefront of transparency standards for the field.

The appointment also deepens a collaboration between SafeBets and SureMark Digital to integrate identity and content verification across the SafeBets platform. The companies expect to share more about their joint work in the months ahead.

“Trust is the foundation of prediction, and few people have done more to make digital trust verifiable than Scott Stornetta,” said Alex Konanykhin, Founder and Chief Executive Officer of SafeBets. “SureMark is the gold standard for digital identity. And having a co-inventor of blockchain’s foundational technology lead our Advisory Council affirms what SafeBets stands for: predictions you can verify, from predictors you can trust. We are honored to have him guide our standards as we build the most credible prediction platform in the world.”

“At first, I was surprised that the CEO of SafeBets would reach out to me. But when I met Alex and came to understand his history of business transparency and his commitment to the highest standards of data integrity, it made complete sense,” said W. Scott Stornetta. “Together, we will establish a new industry high bar for identity, transparency, and auditability. I am glad to join as Chair of the Advisory Council to help establish those standards, standards that the entire field can benefit from.”
