TAIYO YUDEN Launches Advanced Conductive Polymer Capacitors for Automotive Use
TAIYO YUDEN CO., LTD. has recently unveiled its new series of conductive polymer hybrid aluminum electrolytic capacitors, dubbed the "HVX (-J)" and "HTX (-J)" series. These capacitors have been specifically designed to meet the evolving demands of automotive applications, particularly in response to the increasing complexity of power supply circuits in modern vehicles. The capacitors were developed as a next-generation alternative to TAIYO YUDEN's existing HVX and HTX models by adhering to the stringent AEC-Q200 Stress Test Qualification standards that are essential for passive components used in automotive environments.
The new HVX and HTX series capacitors are geared towards noise suppression and power smoothing functionalities within power supply circuits that manage control systems in vehicles. This includes critical functions such as power steering and advanced driver-assistance systems (ADAS), which are increasingly integrated into automobiles as they become more electrified and sophisticated. A key challenge in this sector is the need for capacitors that can handle higher rated ripple currents while maintaining a lower profile for design flexibility. TAIYO YUDEN has risen to this challenge by launching 36 different types of hybrid capacitors. Among these, the "RAHTX331M1TFH0002JX" variant boasts a remarkable 3,400 mArms rated ripple current, representing a 70% increase compared to its predecessor, the "RAHTX331M1TFH0002X."
The series features a compact size range from φ8x10 mm to φ12.5x13.5 mm, allowing manufacturers the necessary flexibility to integrate these components into diverse vehicle designs. Mass production commenced in September 2025 at two facilities: the Shirakawa Plant in Fukushima Prefecture and the Aomori Plant located in Kuroishi City. The capacitors are priced at a competitive 150 yen per unit, ensuring accessibility for automotive manufacturers in need of reliable components.
Hybrid capacitors utilize a combination of conductive polymer and a liquid electrolyte as their internal electrolyte. This unique formulation capitalizes on the low Equivalent Series Resistance (ESR) properties of the conductive polymer, while simultaneously benefiting from the self-repairing abilities of anodic oxide film typical in aluminum electrolytic capacitors. This intelligent design not only enhances the performance of these capacitors but also reinforces their reliability in power circuits subjected to higher demands.
With the progressive electrification of automobiles leading to increased numbers of power circuits for systems such as ADAS, the requirement for compact capacitors that can handle high ripple currents continues to grow. TAIYO YUDEN has significantly optimized its conductive polymer impregnation process, allowing for a more expansive and lower-profile package option that directly addresses these demands. The finished HVX (-J) and HTX (-J) series are engineered with high performance in mind while remaining compliant with industry qualifications needed for modern automotive systems.
Looking forward, TAIYO YUDEN remains committed to innovating products that fulfill current market needs and will continue to enhance its lineup of hybrid capacitors to stay ahead in automotive technology. The company’s approach exemplifies how technology evolution and consumer demands drive advancements in product development, reinforcing TAIYO YUDEN's position as a leader in the electronic components industry. As automotive systems increasingly rely on advanced electronics for functionality and safety, TAIYO YUDEN's contributions prove essential for manufacturers seeking dependable solutions in a competitive market.
